Description

Technical Field

[0001] This utility model belongs to the field of transportation vehicle technology, and in particular relates to a double-layer load-bearing transport vehicle based on brick blanks. Background Technology

[0002] In the production of ceramic tile building materials, after the brick blanks are pressed and formed, they need to be transferred from the forming station to the drying kiln or subsequent processing. Currently, the common transfer methods are still manual handling or semi-automated forklifts. Transporting brick blanks one by one is inefficient, and the weight of stacked brick blanks is huge. Whether it is a 30cm long brick blank commonly sold in the market, the weight after stacking can reach nearly 2 tons, and a 120cm long brick blank can even reach 8 tons. Some simple robotic arms or lifting devices are used for handling, but they still have the disadvantages of poor transportation efficiency and high transportation costs.

[0003] A patent document with patent number "CN212100677U" and utility model title "A Universal Tile Buffer Line" discloses the following features: A universal tile buffer line includes two symmetrically arranged single-sided shelf groups, a linear track arranged below and parallel to the two single-sided shelf groups, and a transport trolley that shuttles back and forth along the linear track. The transport trolley is equipped with a lifting mechanism, which includes a dual-shaft extension motor located in the square vehicle body, follower shafts respectively located at the output ends of the dual-shaft extension motor, and worm gear screw jacks respectively located at one end of the two follower shafts; the material support bracket is located at the output ends of the two worm gear screw jacks, and the dual-shaft extension motor drives the two follower shafts to rotate forward or reverse, thereby simultaneously driving the lifting action of the two worm gear screw jacks to achieve synchronous lifting operation of the material support bracket.

[0004] In the above-disclosed solutions, the lifting mechanism of the trolley uses a screw jack. In the general perception of consumers, screw jacks have very high requirements for the weight of the transported goods. They are usually lightweight goods. Under excessive weight, the motor is prone to distortion and the mechanical structure is easily damaged. Therefore, screw jacks are difficult to use for unified transportation of stacked bricks. Such transportation efficiency is low, the equipment has a short service life, and accidents are prone to occur. Utility Model Content

[0005] The purpose of this utility model is to provide a double-layer load-bearing transport vehicle based on brick blanks, which aims to solve the technical problems of low efficiency and high transportation cost of existing transport trolleys when transporting brick blanks.

[0006] To achieve the above objectives, this utility model provides a double-layer load-bearing transport vehicle based on brick blanks, used to support brick blanks and transport them to a storage area. It includes a base, on which a hydraulic power source and several guide columns evenly arranged front to back are mounted. Each guide column is connected to a support rod assembly. The hydraulic power source is connected to the support rod assembly to drive it to move up and down along the direction of the guide columns. The support rod assembly is a double-layer structure consisting of an upper support rod and a lower support rod, both of which have multiple through-holes along the front-to-back direction. Each through-hole is fitted with a crossbar, the two ends of which extend out from the sides of the upper and lower support rods respectively to form a left support arm and a right support arm.

[0007] Furthermore, the support rod assembly also includes a middle support rod, which is connected between the upper support rod and the lower support rod; and the middle support rod is hollow inside, and is sleeved on the guide column and moves up and down along the guide column under the drive of the hydraulic power source.

[0008] Furthermore, the upper ends of both the left and right support arms are connected to soft rubber pads for providing cushioning.

[0009] Furthermore, a gap is provided between two adjacent left arms or two right arms arranged horizontally.

[0010] Furthermore, a gantry frame is provided on the base, and a number of guide columns evenly arranged front and back are connected between the gantry frame and the base.

[0011] Furthermore, the front and rear ends of the support rod assembly are provided with clearance spaces between them and the gantry frame, and the front and rear ends of the support rod assembly are connected to protective covers, which extend into the clearance spaces.

[0012] Furthermore, the base is provided with pulleys and a drive motor on both sides. The pulleys are provided in two sets, front and rear. The drive end of the drive motor is connected to a transmission rod, and the two ends of the transmission rod are respectively connected to the pulleys to drive the same set of pulleys to rotate.

[0013] Furthermore, the hydraulic power source is provided with a set.

[0014] Furthermore, a clearance space is provided between the longitudinally arranged left or right support arms.

[0015] The above-mentioned technical solutions of the double-layer load-bearing transport vehicle based on brick blanks provided in this embodiment of the utility model have at least one of the following technical effects:

[0016] In this design, the initial transport vehicle uses a robotic arm or forklift to stack freshly produced brick blanks sequentially onto the left and right support arms of the upper and lower support rods. Once a designated quantity is stacked, the transport vehicle carrying the brick blanks moves to the target storage area. After the transport vehicle is positioned, the brick blanks are aligned with the target placement point, and the support rod assembly drives the support arms and brick blanks to descend smoothly. The support arms move in a staggered motion relative to the storage area, securely placing the brick blanks in the target position. After the support arms are completely detached from the brick blanks, the transport vehicle returns to its starting position, awaiting the next work cycle. By relying on the support arms at both ends of the transport vehicle to transfer the brick blanks to the brick storage rack, the conveying efficiency is improved and the transportation cost is reduced.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0037] In one embodiment of this utility model, such as Figure 1-2 As shown, a double-layer transport vehicle based on brick blanks is provided for supporting and transporting brick blanks to a storage area. The transport vehicle includes a base 100, on which a lifting mechanism 200 and several guide columns 120 evenly arranged front and rear are provided. Each guide column 120 is connected to a common support rod assembly 140. The lifting mechanism 200 is a hydraulic power source 210, which is connected to the bottom end of the lower support rod 143 to drive the entire support rod assembly 140 to move up and down along the guide columns 120. The support rod assembly 140 is a double-layer structure composed of an upper support rod 141 and a lower support rod 143. Both have multiple through-holes 150 along the front and rear direction. A crossbar passes through the through-holes 150, and the two ends of the crossbar extend out to the two sides of the support rod assembly 140 to form a left support arm 130 and a right support arm 131, respectively.

[0038] like Figure 2 As shown, the initial transport vehicle uses a robotic arm or forklift to stack the newly produced brick blanks sequentially onto the left and right support arms 130 and 131 of the upper support 141 and the left and right support arms 130 and 131 of the lower support 143. Once the designated quantity is reached, the transport vehicle carrying the brick blanks moves to the target storage area. Figure 3-4 As shown, the storage area for brick blanks is a brick storage rack group 500 equipped with receiving rods. The brick storage rack group 500 includes at least one row of several brick storage racks 510 arranged longitudinally. Each brick storage rack 510 includes a column 20, and two layers of parallel left receiving rods 530 and right receiving rods 540 are arranged on both sides of the column 20. The upper layer is divided into a left first receiving rod 531 and a right first receiving rod 541, and the lower layer is divided into a left second receiving rod 532 and a right second receiving rod 542. A left first storage area 550 is formed above the left first receiving rod 531, a right first storage area 570 is formed above the right first receiving rod 541, a left second storage area 560 is formed between the left first receiving rod 531 and the left second receiving rod 532, and a right second storage area 580 is formed between the right first receiving rod 541 and the right second receiving rod 542. The vertically arranged columns 20 are spaced at the same distance from each other. A left transport guide rail 590 is provided below the left support rod 530, and a right transport guide rail 591 is provided below the right support rod 540.

[0039] like Figure 4 As shown, the transport vehicle travels along the left transport rail 590 and the right transport rail 591 from the middle of two adjacent brick storage racks 510. Taking the left support arm 130 of the transport vehicle as an example, at this time, the upper left support arm 130 of the transport vehicle is higher than the right first receiving rod 541, and the lower left support arm 130 is located between the right first receiving rod 541 and the right second receiving rod 542. From a top-down perspective, the left support arm 130 and the right receiving rod 540 overlap. After reaching the positioning point, the hydraulic power source 210 drives the left support arm 130 to descend smoothly. The support arm and the receiving rod move in a staggered manner, moving the brick blanks of the upper left support arm 130 to the right first storage area 570, and the brick blanks of the lower left support arm 130 to the right second storage area 580. After the support arm is completely detached from the brick blanks, the transport vehicle returns to the starting position and waits for the next work cycle. The right support arm 131 is handled in the same way. A transport vehicle equipped with two layers of brick blanks passes through the gap 700 between the two brick storage racks 510, and transfers the brick blanks onto the brick storage racks 510 by means of the support arms at both ends, which improves the conveying efficiency and reduces the transportation cost.

[0040] Preferably, such as Figure 1-2 As shown, the support rod assembly 140 also includes a middle support rod 142, which connects the upper support rod 141 and the lower support rod 143. The middle support rod 142 is hollow inside and is sleeved on the guide post 120, moving up and down along the guide post 120 under the drive of the hydraulic power source 210. The middle support rod 142 is in close contact with and slidably connected to the guide post 120, enhancing the stability of the support rod assembly 140.

[0041] Preferably, such as Figure 1 As shown, the upper ends of the left support arm 130 and the right support arm 131 are both connected to soft rubber pads 160 for providing cushioning. The brick blanks supported on the support arms are prone to bumping into the support arms, so the soft rubber pads 160 can protect the brick blanks.

[0042] Preferably, a gap 700 is provided between the horizontally arranged and adjacent left support arm 130 or right support arm 131.

[0043] Preferably, a clearance space 710 is provided between the longitudinally arranged left support arm 130 or right support arm 131.

[0044] Preferably, such as Figure 1-2As shown, a gantry frame 110 is mounted on the base 100, and several guide columns 120 arranged evenly in a front-to-back pattern are connected between the gantry frame 110 and the base 100. Clearance spaces 300 are provided between the front and rear ends of the support rod assembly 140 and the gantry frame 110, and protective covers 310 are connected to both ends of the support rod assembly 140, extending into the clearance spaces 300. The gantry frame 110 improves the overall stability of the transport vehicle. The clearance spaces 300 between the support rod assembly 140 and the gantry frame 110, when the support rod assembly 140 moves relative to the gantry frame 110, could easily cause injury to workers by pinching or colliding. Therefore, the protective covers 310 are provided to improve the safety factor.

[0045] Preferably, such as Figure 6 As shown, the left support arm 130 and the right supporting rod 541, and the right support arm 131 and the left supporting rod 531 are staggered in various ways. From the perspective of the top view projection, taking the left support arm 130 as an example, for example: 1. Several left support arms 130 supporting the goods are all set between the two right supporting rods 541; 2. At least one left support arm 130 is set between the two right supporting rods 541, and at least one is set outside the two right supporting rods 541; 3. All left support arms 130 are set on both sides outside the two right supporting rods 541. All three of the above methods can enable the left support arm 130 to move up and down between the two right supporting rods 541 to achieve the effect of transferring the brick blank onto the supporting rod 540.

[0046] Preferably, the support rod assembly of the transport vehicle can be a single-layer or double-layer structure, and the corresponding support arm can be single-layer or double-layer, but cannot be set to more than three layers. This is because for brick blanks that are measured by tonnage after being stacked, more than three layers place very demanding requirements on the rigid conditions of the transport vehicle's pulley 400, support rod assembly 140, and lifting mechanism 200, which are prone to breakage, deformation, tilting, etc. during transportation, leading to the collapse of the brick blanks.

[0047] Preferably, such as Figure 1-2 As shown, there are two sets of pulleys 400, which are arranged sequentially at the front and rear ends of the base 100. The base 100 is equipped with a drive motor 410, the drive end of which is connected to a transmission rod 420. The two ends of the transmission rod 420 are respectively connected to the pulleys 400 to drive the same set of pulleys 400 to rotate.

[0048] In another embodiment, such as Figure 5As shown, a single-arm transport vehicle is also provided, including a transport base 600. A support 610 is provided on one upward-facing side of the transport base 600. At least one first connecting arm 620 extends from the support 610 toward the brick storage rack assembly 500 to support goods. The left end of the first connecting arm 620 is connected to the support 610, and its right end points toward the left receiving rod 530. If the longitudinal transport vehicle, after changing direction, enters the right transport guide rail 591, the left end of the first connecting arm 620 points toward the right receiving rod 540, and its right end is connected to the support 610. Taking the first layer of the brick storage rack 510 as an example, the first connecting arm 620 extends into the left first storage area 550, and the first connecting arm 620 moves in a staggered manner with either the left first receiving rod 531 or the right first receiving rod 541, moving the brick blanks onto the corresponding brick storage rack 510.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
