Description

Technical Field

[0001] The invention relates to the field of building transportation devices, and in particular to a simple and safe partition board transportation and installation machine. Background Art

[0002] Partition board, the full name is lightweight strip board for building partition, mainly includes glass fiber reinforced cement strip board, glass fiber reinforced gypsum hollow strip board, steel wire (wire mesh) reinforced cement strip board, light concrete strip board, composite sandwich lightweight strip board, etc. It is generally used as the main material for non-load-bearing internal partition walls of industrial buildings, residential buildings, and public construction projects. It has the advantages of moisture-proof, earthquake-resistant and sound-insulating, fireproof and heat-insulating, small footprint, good strength, and convenient construction.

[0003] However, since partition boards are generally long and heavy, it is difficult for one person to carry them, and usually two people work together to carry them. When using traditional transport vehicles to transport them, two people are required to carry the partition boards to the vehicle. After arriving at the designated location, more people will use their strength to lift the partition boards to a vertical state for use. Since the partition boards are heavy, in the process of lifting them up, not only do they require the cooperation of multiple people, but they also need to apply force evenly to prevent the partition boards from tilting to one side. However, despite this, on construction sites, partition boards often tilt to one side and injure people, threatening the lives of the operators.

[0004] There are also partition board installation vehicles with a high degree of mechanization in the prior art. The partition board is clamped by a forward clamp saw, and then the partition board is rotated 90 degrees and erected by a 360-degree rotating shaft. For example, the patent number CN201520206594.1, entitled Partition Board Transport and Installation Machine, is a reference to this prior art. However, this type of partition board installation vehicle can only grab and rotate a partition board individually, and it takes a very long time to operate a partition board, which is inefficient. In addition, it cannot be used for transportation, and the cost is high. General construction companies are not willing to purchase it. Summary of the invention

[0005] In view of the problems of high labor consumption, low efficiency and potential safety hazards in the transportation and installation process of the above-mentioned partition boards, the present invention provides a simple and safe partition board transportation and installation machine, which can conveniently and safely transport the partition boards to the designated locations and use a lifting device to erect the partition boards. It can be operated by one person, which is simple and safe.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is:

[0007] A simple and safe partition board transport and installation machine comprises a chassis, a transport board, a lifting device and an operating rod. The chassis comprises a front crossbeam, a rear crossbeam and side longitudinal beams on both sides. At least a wheel is connected below the side longitudinal beam. When the partition board is erected, the wheel center below the side longitudinal beam will serve as the rotation center of the partition board transport and installation machine, so that the partition board can be flipped forward. The upper part of the chassis is directly or indirectly connected to the transport board through a vertical beam. The lower part of the transport board is connected to a lifting device. The lifting device can push the transport board to rotate from the rear crossbeam to the front crossbeam, so as to erect the partition board. The operating rod is connected to the side of the chassis, and a button part is provided on it for controlling the action of the lifting device. Preferably, the height of the button part on the operating rod is suitable for the chest height of the human body, which is convenient for manual operation and prevents the partition board from being hit by the partition board when it is carried to the transport board. Because the partition board is long, the operating rod should not interfere with the transport board in the vertical plane.

[0008] Furthermore, the distance between the wheels below the side longitudinal beam and the front cross beam accounts for 1 / 3 to 1 / 2 of the total length of the side longitudinal beam. The distance between the front cross beam and the wheels below the side longitudinal beam is a major feature of the present invention. Through this special distance setting, when the lifting device flips the transport board forward, the center of gravity of the partition board continues to move forward, and the front cross beam will quickly contact the ground, supporting the partition board transport and installation machine together with the wheels. Moreover, after the front cross beam touches the ground, the inclination of the transport board is greater, which is convenient for the partition board to fall quickly to the designated position. In addition, after the front cross beam contacts the ground as a whole, the friction between the partition board transport and installation machine and the ground will be greatly increased, making the forward tilting action of the partition board more stable, and can effectively prevent the partition board from tilting to the side. This is also far beyond the reach of ordinary transport vehicles that rely solely on wheels to support the upper body.

[0009] Moreover, in the above parameters, the distance between the wheel below the side longitudinal beam and the front cross beam is at least 1 / 3 of the total length of the side longitudinal beam, ensuring that the front cross beam has a certain amount of rollover space. If this value is too small, the support effect will be greatly reduced, and there is a risk of rollover. The distance between the wheel below the side longitudinal beam and the front cross beam is at most 1 / 2 of the total length of the side longitudinal beam, ensuring that the overall center of gravity of the partition board transporter is horizontally located backward from the center of the wheel below the side longitudinal beam during the transportation of partition boards, preventing the problem of the front cross beam contacting the ground due to the overall center of gravity being too forward in the horizontal direction.

[0010] The simple and safe partition board transport and installation machine as described above has a fixed vertical beam at least distributed at the front cross beam, and the fixed vertical beam is hinged to the front end of the transport board directly or through a connecting frame. When the lifting device flips the transport board forward, the transport board rotates around the hinge point above the front cross beam.

[0011] As another embodiment, a turning frame is further provided between the chassis and the transport plate, the transport plate and the turning frame are hinged together at the front end, the lower end of the turning frame is connected to the chassis via a fixed vertical beam and a movable vertical beam, the fixed vertical beam and the movable vertical beam are respectively located on both sides of the chassis, and the movable vertical beam is rotatably connected to the chassis. The movable vertical beam can drive the turning frame and the transport plate above to rotate around the chassis together.

[0012] Preferably, a lifting device is connected between the overturning frame and the chassis, and the overturning frame and the transport plate can be rotated around the chassis together by controlling the lifting device.

[0013] Furthermore, a reinforcing plate is provided between the movable vertical beam and the turning frame. During the test phase, due to the frequent turning of the movable vertical beam, the force at this place is relatively large, which may cause the movable vertical beam to break. After adding the reinforcing plate, the problem of breaking at the junction of the movable vertical beam and the turning frame is eliminated.

[0014] Furthermore, the transport board or the turning frame is provided with one or more shovels on one side of the movable vertical beam, and the shovels are perpendicular to the upper surface of the transport board or the turning frame and are arranged upward. Before adding the shovels, the partition board transport and installation machine can be used to transport the partition boards from the lower floor to the upper floor, and after arriving at the designated position, the turning frame and the transport board can be turned to one side. After adding the shovels, the partition boards on the ground can be shoveled up and turned over to the top of the transport board, which is more functional.

[0015] The simple and safe partition board transport and installation machine as described above has more than 3 wheels. Two wheels are provided at the front lower part of the chassis side longitudinal beam, and one or more wheels can be provided at the rear cross beam. Preferably, the wheels are controlled by a motor, and the control switch is provided at the button part of the joystick.

[0016] The simple and safe partition board transport and installation machine described above has one or two support seats rotatably connected to both sides of the chassis, and the support seats are connected to the chassis through a retracting device, and the maximum length of the support seats is greater than the length of the chassis from the bottom of the wheels. The support seats are usually in a retracted state. When the partition board is transported to a designated location and is ready to be erected, the support seats can be pushed forward by the retracting device and supported on the ground, and the friction between the partition board transport and installation machine and the ground can be increased together with the front crossbeam to prevent the partition board transport and installation machine from falling backwards during the erection process. The retracting device can use various telescopic cylinders or spring devices.

[0017] Preferably, the plane formed by the lower front end of the chassis and the bottom of the wheel below the side longitudinal beam is tangent to the circle formed by the rotation trajectory of the support seat. It has been verified that in this state, the support seat requires the least support force, and the partition board transport and installation machine has the best stability.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. The simple and safe partition board transportation and installation machine of the present invention can realize many actions such as transporting partition boards from downstairs to upstairs, flipping partition boards from the ground onto the transportation board, flipping partition boards forward from the transportation board, etc., covering all stages of the use of partition boards, with comprehensive functionality and higher efficiency.

[0020] 2. The simple and safe partition board transport and installation machine of the present invention has a distance between the wheels below the side longitudinal beam and the front cross beam that accounts for 1 / 3 to 1 / 2 of the total length of the side longitudinal beam. With this special distance setting, when the lifting device flips the transport board forward, the center of gravity of the partition board continuously moves forward, and the front cross beam will quickly contact the ground, supporting the partition board transport and installation machine together with the wheels. Moreover, after the front cross beam touches the ground, the inclination of the transport board is greater, which facilitates the partition board to fall quickly to the designated position. In addition, after the entire front cross beam contacts the ground, the friction between the partition board transport and installation machine and the ground will be greatly increased, making the forward tilting action of the partition board more stable, and can effectively prevent the partition board from tilting to the side. This is also far beyond the reach of ordinary transport vehicles that rely solely on wheels to support the upper body.

[0021] 3. The simple and safe partition board transport and installation machine of the present invention can be equipped with two sets of lifting devices between the chassis and the transport board, which are respectively used for the side flipping and front flipping of the transport board. The overall structure is compact and occupies little space, which is very suitable for moving between rooms.

[0022] 4. The simple and safe partition board transport and installation machine of the present invention has one or two support seats rotatably connected to both sides of the chassis, and the support seats are connected to the chassis through a folding device, and the maximum length of the support seats is greater than the length of the chassis from the bottom of the wheels. The support seats are usually in a folded state. When the partition board is transported to a designated location and is ready to be erected, the support seats can be pushed forward by the folding device and supported on the ground, and the friction between the partition board transport and installation machine and the ground can be increased together with the front crossbeam to prevent the partition board transport and installation machine from falling back during the erection process, thereby ensuring the safety of the partition board transport and installation machine.

[0040] The exemplary embodiments of the present disclosure will be described in more detail below in conjunction with the accompanying drawings. It should be noted that these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. The present disclosure can be implemented in various forms and should not be limited by the embodiments described herein.

[0041] The directions “front”, “back”, “left”, “right”, etc. mentioned in the present invention are only used to express relative positional relationships and are not subject to any specific direction reference in practical applications. Therefore, they cannot be understood as limitations on the present invention.

[0042] Example 1

[0043] See also Figure 1-Figure 3 , Figure 1-Figure 3 The structural schematic diagram of the simple and safe partition board transport and installation machine shown in this embodiment includes a chassis 1, a transport board 2, a lifting device and an operating lever 4, the chassis 1 includes a front crossbeam 101, a rear crossbeam 102 and side longitudinal beams 103 on both sides, and a wheel 104 is connected under each side longitudinal beam 103, and the wheel 104 is driven by a motor 105. The motor 105 and the power supply 107 are arranged on the chassis 1, and the switches of the motor 105 and the power supply 107 are connected to the operating lever 4.

[0044] Furthermore, a certain distance is maintained between the wheel 104 and the front cross beam 102. When the partition board is erected, the center of the wheel 104 below the side longitudinal beam 103 will serve as the rotation center of the partition board transport and installation machine, so that the partition board can be flipped forward more easily.

[0045] Furthermore, the upper part of the chassis 1 is connected to the transport board 2 through a fixed vertical beam 109. In this embodiment, the fixed vertical beams 109 include four beams, two of which are connected to the front cross beam 101, and the other two are connected to the rear cross beam 102. An upper cross beam 110 is also connected to the top of the two fixed vertical beams 109 at the front cross beam 101, and the upper cross beam 110 is hinged to the transport board 2 through a hinge 22. A lifting device is connected to the lower part of the transport board 2, and the lifting device can push the transport board 2 to rotate from the rear cross beam 102 to the front cross beam 101, so as to erect the partition board. The operating rod 4 is connected to the side of the chassis 1, and a button part 41 is provided on it for controlling the action of the lifting device. Preferably, the height of the button part 41 on the operating rod 4 is suitable for the chest height of the human body, which is convenient for manual operation and prevents the partition board from being hit by the partition board when it is carried to the transport board 2. Since the partition board is relatively long, the operating rod 4 should not interfere with the transport board 2 in the vertical plane.

[0046] In this embodiment, the length of the wheel 104 below the side longitudinal beam 103 from the front cross beam 101 accounts for 1 / 3 to 1 / 2 of the total length of the side longitudinal beam 103, and one or two wheels 104 are set below or behind the rear cross beam 102. The stable operation of the partition board transport and installation machine is ensured by more than three wheels 104. The distance relationship between the front cross beam 101 and the wheels 104 below the side longitudinal beam 103 is set as a major feature of the present invention. Through this special distance setting, when the lifting device flips the transport board 2 forward, the center of gravity of the partition board continues to move forward, and the front cross beam 101 will quickly contact the ground and support the partition board transport and installation machine together with the wheels 104. Moreover, after the front cross beam 101 lands, the inclination of the transport board 2 is greater, which is convenient for the partition board to fall quickly to the specified position. In addition, after the front cross beam 101 contacts the ground as a whole, the friction between the partition board transport and installation machine and the ground will be greatly increased, making the forward tilting action of the partition board more stable, and can effectively prevent the partition board from tilting to the side. This is also far beyond the reach of ordinary transport vehicles that only rely on wheels 104 to support the upper load.

[0047] Moreover, in the above parameters, the distance between the wheel 104 below the side longitudinal beam 103 and the front cross beam 101 is at least 1 / 3 of the total length of the side longitudinal beam 103, ensuring that the front cross beam 101 has a certain amount of turning space. If this value is too small, the supporting effect will be greatly reduced, and there is a risk of overturning. The distance between the wheel 104 below the side longitudinal beam 103 and the front cross beam 101 is at most 1 / 2 of the total length of the side longitudinal beam 103, ensuring that the overall center of gravity of the partition board conveyor is horizontally located backward from the center of the wheel 104 below the side longitudinal beam 103 during the transportation of partition boards, preventing the problem of the front cross beam 101 contacting the ground due to the overall center of gravity being too far forward in the horizontal direction.

[0048] In this embodiment, the transport plate 2 is a frame structure assembled from rectangular tubes and includes a rear tail beam 21 and an upper plate 23. The rear tail beam 21 is located above the front cross beam 101 of the chassis 1 and is hinged to the upper cross beam 110 through a hinge 22. Figure 3 The top of the transport plate 2 is an upper plate 23, which is used to place partition boards and prevent debris from falling from the partition boards from falling into the motor 105 below. Moreover, by laying the upper plate 23, the partition board transport and installation machine can be used to transport building materials and workers in addition to transporting partition boards, and has more comprehensive functions and is more flexible to use on construction sites.

[0049] Furthermore, a lifting device is connected below the transport plate 2, and the lifting device can be a telescopic cylinder commonly used on the market, such as a hydraulic cylinder, an electric cylinder, etc. The lifting device in this embodiment adopts a lifting oil cylinder 3, and the corresponding oil tank 106, a solenoid valve, etc. are installed on the chassis 1.

[0050] Further, the lower part of the lifting cylinder 3 is mounted on the cylinder fixing seat 113 welded above the first cylinder support plate 108 at the rear of the chassis 1, see Figure 1 The upper part is mounted on the oil cylinder fixing seat 113 below the front part of the transport plate 2, see Figure 2 .

[0051] In this embodiment, the operating rod 4 is an L-shaped rod, which is led out from one end of the rear cross beam 102. The vertical plane where the operating rod 4 is located is kept at a certain distance from the edge of the transport board 2 to prevent it from being hit by the partition board on the transport board 2.

[0052] In this embodiment, a support seat 112 is rotatably connected to each side of the side longitudinal beam 103 of the chassis 1. The two support seats 112 are connected together by a support shaft 111, and the axis of the support shaft 111 is parallel to the center line of the two front wheels 104, ensuring that the two support seats 112 can synchronously support the partition board transport and installation machine. The support seat 112 is connected to the chassis 1 through a retracting device, and the retracting device can adopt various telescopic cylinders or spring devices. In this embodiment, a hydraulic cylinder (not shown in the figure) is used to drive the retracting device to move, and the driving switch is set on the button part 41 of the joystick 4. The maximum length of the support seat 112 is greater than the length of the chassis 1 from the bottom of the wheel 104.

[0053] Furthermore, the support base 112 includes two or more steel pipes and a flat plate, and the ends of the steel pipes are fixed on the flat plate. When the support base 112 rotates forward, the front end of the flat plate first touches the ground, and when the entire flat plate is parallel to the ground, the support base 112 will support the rear half of the partition board transport and installation machine.

[0054] See also Figure 4-Figure 6 The support seat 112 is usually in a folded state. When the partition board is transported to the designated location and is ready to be erected, the support seat 112 can be pushed forward by the folding device and supported on the ground, and cooperate with the front crossbeam 101 to increase the friction between the partition board transport and installation machine and the ground, preventing the partition board transport and installation machine from moving backwards during the erection process, thereby ensuring safety during use.

[0055] Preferably, the plane formed by the lower front end of the chassis 1 and the bottom of the wheel 104 below the side longitudinal beam 103 is tangent to the circle formed by the rotation trajectory of the support seat 112. It has been verified that in this state, the support seat 112 requires the least support force, and the partition board transport and installation machine has the best stability.

[0056] Example 2

[0057] See also Figure 7-Figure 9As another embodiment, a turnover frame 5 is further provided between the chassis 1 and the transport plate 2. The transport plate 2 is hinged to the front end of the turnover frame 5. The lower end of the turnover frame 5 is connected to the chassis 1 through a fixed vertical beam 109 and a movable vertical beam 54. The fixed vertical beam 109 and the movable vertical beam 54 are respectively located on both sides of the chassis 1. Fig.10 and Fig.11 The fixed vertical beam 109 is located on the right side of the partition board transport and installation machine and is fixedly connected to the chassis 1. The movable vertical beam 54 is located on the left side of the partition board transport and installation machine and is fixedly connected to the turning frame 5. The movable vertical beam 54 is rotationally connected to the chassis 1 through the turning shaft 56. The movable vertical beam 54 can drive the turning frame 5 and the transport board 2 above to rotate around the chassis 1.

[0058] Furthermore, a turning cylinder 6 is connected between the turning frame 5 and the chassis 1. The turning cylinder 6 moves toward the side of the partition board transport and installation machine. The upper part of the turning cylinder 6 is installed on the second cylinder support plate 51 at the lower part of the turning frame 5, and the lower part is installed on the third cylinder support plate 52 of the chassis 1. The turning cylinder 6 can be controlled to realize that the turning frame 5 and the transport board 2 are rotated to the side around the chassis 1 together, which can be used to lower the partition board to the side.

[0059] Preferably, in order to enable the lifting cylinder 3 and the turning cylinder 6 to work separately without interfering with each other, the turning cylinder 6 is located at the rear of the lifting cylinder 3. A lower bracket 53 extends downward from the rear of the turning frame 5, and the lower bracket 53 is located in front of the turning cylinder 6. The lower part of the lifting cylinder 3 is installed at the lower part of the lower bracket 53, and the upper part is installed on the front lower cross beam of the transport plate 2.

[0060] Furthermore, a reinforcing plate 55 is provided between the movable vertical beam 54 and the turning frame 5. During the test phase, due to the frequent turning of the movable vertical beam 54, the force at this place is relatively large, which may cause the movable vertical beam 54 to break. After adding the reinforcing plate 55, the problem of breaking at the junction of the movable vertical beam 54 and the turning frame 5 is eliminated.

[0061] Furthermore, the transport board 2 or the turning frame 5 is provided with two shovel plates 24 on one side of the movable vertical beam 54, and the shovel plates are perpendicular to the upper surface of the transport board 2 or the turning frame 5 and are arranged upward. Before the shovel plates 24 are added, the partition board transport and installation machine can be used to transport the partition boards from the lower floor to the upper floor, and after arriving at the designated position, the turning frame 5 and the transport board 2 can be turned to one side. After the shovel plates 24 are added, the partition boards on the ground can be shoveled up and turned over to the top of the transport board 2, which is more functional.

[0062] Fig.10 and Fig.11 The figure shows the state of the partition board transport and installation machine being turned sideways for use, at which time the turning frame 5 and the transport board 2 are turned sideways together. Fig.12 and Fig.13The state diagram of the partition board transport installation machine when erecting the partition board forward, at this time, only the turning cylinder 6 is started to push the transport board 2 forward. At the same time, the support seat 112 is propped up together.

[0063] By adding the flip frame 5, the partition board transport and installation machine can realize many actions such as transporting partition boards from downstairs to upstairs, flipping partition boards from the ground onto the transport board, flipping partition boards forward from the transport board, etc., covering all stages of the use of partition boards, with comprehensive functionality and higher efficiency.

[0064] Other features not mentioned in this embodiment are the same as those in Embodiment 1 and will not be described in detail.

[0065] Example 3

[0066] In order to further ensure the safety when erecting partition boards using the partition board transport and installation machine, one or more telescopic rods may be provided behind the transport board 2. Correspondingly, a corresponding number of hollow pipes are provided on the transport board 2. The hollow pipes may be rectangular pipes, round pipes, etc. The telescopic rods match the inner dimensions of the hollow pipes, and are pulled out when in use and inserted into the hollow pipes when not in use. Preferably, the head of the telescopic rod is slightly larger to prevent the entire telescopic rod from completely entering the hollow pipe and being difficult to be pulled out.

[0067] Specifically, when transporting the partition board, first pull the telescopic pull rod out of the hollow pipe, and then place the partition board on the transport board 2. Under the influence of the gravity of the partition board, the partition board and the telescopic pull rod are in a compacted state. At this time, the extended telescopic pull rod is equivalent to extending the length of the transport board 2, which is beneficial to the stability of the partition board transportation. When the partition board is erected forward, the partition board in front of the transport board 2 touches the ground first. Because the partition board is long, if the length of the part of the partition board that exceeds the transport board 2 after it touches the ground is greater than the length of the transport board 2, the partition board may tip over. At this time, the telescopic pull rod has the effect of lengthening the length of the transport board 2, which can effectively prevent the risk of the partition board tipping over.

[0068] Example 4

[0069] When the partition board transport and installation machine erects the partition board, the partition board will slide from the transport board 2 to the ground under the action of the lifting device. In order to increase the sliding speed of the partition board, two or more rollers can be arranged behind the transport board 2, and the upper plane of the rollers is not lower than the upper plane of the transport board 2, preferably slightly higher than the upper plane of the transport board 2. Preferably, the rollers behind the transport board 2 are symmetrically distributed to keep the center of gravity of the partition board stable during the sliding process.

[0070] Other features not mentioned in this embodiment may be the same as those in Embodiment 1 or 2 and will not be described in detail.

[0071] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or additions, subtractions or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
