Description

Technical Field

[0001] This invention relates to the field of material handling equipment technology, and more specifically to a height-adaptive transportation vehicle. Background Technology

[0002] In electromechanical installation projects, the transportation of large equipment and components such as chiller units, water pumps, and prefabricated modules to the construction site is often involved. In related technologies, rollers are typically used as auxiliary tools. The rollers are placed horizontally on the equipment foundation, and the equipment modules are pushed along the rollers to transport them. In some installation sites, the height of the chiller unit is much higher than the equipment foundation. In such cases, a support plate needs to be laid on the equipment foundation to raise it to the same height as the chiller unit, facilitating the movement of the rollers.

[0003] Regarding the aforementioned technologies, for construction sites with long transportation distances, it is necessary to lay a large number of mats or alternately lay mats repeatedly, which consumes a lot of time when laying mats. Furthermore, if the mats are not laid flat, the rollers are prone to tilting, causing the equipment modules to tip over. Therefore, there are problems of low transportation efficiency and insufficient stability of the transportation vehicles. Summary of the Invention

[0004] The purpose of this invention is to provide an adaptive altitude transportation vehicle to solve the problems of low transportation efficiency and insufficient stability of transportation vehicles.

[0005] To achieve the above objectives, the present invention provides an adaptive altitude transportation vehicle using the following technical solution:

[0006] An adaptive height transport vehicle includes a sliding base, a lifting component, an adjustable clamp, and a retainer. A turntable is rotatably mounted on the top surface of the sliding base. The lifting component is fixedly connected to the turntable. The adjustable clamp is fixedly connected to the end of the lifting component away from the turntable. A cross-shaped clamping hole is provided in the center of the adjustable clamp. The retainer is detachably fitted around the turntable and extends to the side walls of the sliding base. Guide wheels are rotatably mounted on the inner wall of the retainer, and the guide wheels are used to abut against the side walls of the equipment foundation.

[0007] As an optimization of an adaptive height transportation tool, the adjustable clamp includes a circular base and four right-angled sector disks. The circular base is fixedly connected to the end of the lifting member away from the sliding base. The right-angled sector disks are slidably connected to the circular base. The four right-angled sector disks are spaced apart along the circumference of the circular base, and a gap is provided between each pair of right-angled sector disks. The four gaps are interconnected to form a cross clamping hole.

[0008] As an optimization of an adaptive altitude transportation tool, a first screw is rotatably embedded on the circular chassis, and a second screw is rotatably embedded on the right-angled sector disk. The second screw is perpendicular to the first screw. A linkage block is provided on the circular chassis. One end of the linkage block is sleeved on the periphery of the first screw, and the other end of the linkage block is sleeved on the periphery of the second screw.

[0009] As an optimization of an adaptive height transport tool, the retainer is provided with a sleeve hole, the diameter of which is greater than or equal to the diameter of the turntable. Two limiting plates are fixedly connected inside the retainer, and the two limiting plates abut against the two sides of the sliding base respectively.

[0010] As an optimization of an adaptive height transportation tool, the limiting plate has a tenon column vertically arranged on the side near the sliding base, and the side wall of the sliding base has a tenon hole vertically arranged, with the tenon column inserted into the tenon hole.

[0011] As an optimization of an adaptive height transport vehicle, the inner wall of the cage is fixedly connected to a tension spring, and the end of the tension spring away from the inner wall of the cage is fixedly connected to the limiting plate.

[0012] As an optimization of an adaptive height transportation tool, the inner wall of the cage is slidably embedded with a telescopic rod, the guide wheel is rotatably connected to one end of the telescopic rod near the sliding base, and the other end of the telescopic rod is provided with a locking bolt.

[0013] As an optimization of an adaptive height transportation tool, the bottom surface of the sliding base is rotatably connected to rollers, and an even number of rollers are provided, with multiple rollers arranged side by side on the bottom surface of the sliding base.

[0014] As an optimization of an adaptive height transportation tool, the lifting component is equipped with a height sensor. The lifting component is a multi-stage hydraulic jack, and the lifting component includes at least three stages of jacking rods, with each stage of jacking rod being no more than 15cm.

[0015] As an optimization of an adaptive height transportation tool, the sliding base is equipped with a distance sensor and an indicator light at both the front and rear ends. The indicator light at one end of the sliding base is connected to the distance sensor at the other end of the sliding base.

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 invention based on the specific circumstances.

[0025] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail below.

[0027] This application provides an adaptive altitude transportation vehicle, which adopts the following technical solution:

[0028] Reference Figure 1 and Figure 2 The transport vehicle includes a sliding base 1, a lifting component 2, an adjustable clamp 3, and a retainer 4. The sliding base 1 serves as the sliding foundation, and is placed on the equipment foundation to slide along the transport path. Furthermore, rollers 11 are rotatably connected to the bottom surface of the sliding base 1. The number of rollers 11 is even, and the even number of rollers 11 are arranged side-by-side on the sliding base 1. In this embodiment, eight rollers 11 are rotatably mounted on the bottom surface of the sliding base 1, arranged in pairs side-by-side. Four sets of rollers 11 are rotatably connected to the bottom surface of the sliding base 1. Compared to other rollers, the rollers 11 can increase the contact area between the sliding base 1 and the roadbed guide rail, evenly distributing the load of the sliding base 1 to the ground, thereby improving the load-bearing capacity of the sliding base 1. In addition, the side-by-side arrangement of the rollers 11, through load balancing on both sides, allows the sliding base 1 to slide more smoothly on the equipment foundation.

[0029] Reference Figure 1 and Figure 3A turntable 12 is embedded in the top surface of the sliding base 1. The turntable 12 rotates around its own center, adjusting the orientation of the object carried on the sliding base 1 to adapt to different turning requirements. Lifting components 2 are fixedly mounted on the turntable 12. Each lifting component 2 is equipped with a height sensor (not shown in the figure), which monitors the distance between the top surface of the lifting component and the ground, transmitting signals to a chip installed on the lifting component 2. The chip on the lifting component 2 controls the upward or downward stroke of the lifting component 2. In practical applications, communication is established between the lifting components 2 installed at different locations on the equipment module. Each lifting component adapts to local ground unevenness, while the top surfaces of all lifting components 2 remain at the same horizontal level, ensuring the equipment module remains on the same horizontal plane. This adapts to complex road conditions and improves the flexibility and stability of the transportation vehicle.

[0030] Furthermore, the lifting component 2 is a multi-stage hydraulic jack, and the lifting component 2 includes at least three stages of jack rods 21. The height of each stage of jack rod 21 is no more than 15cm. In this embodiment, the height of each stage of jack rod 21 is 10cm. The lifting component 2 can be folded into one layer, occupying only 10cm of height space, reducing the footprint and facilitating transportation. It can also be unfolded and extended to a height of 30cm to meet the height requirements of the assembly environment.

[0031] Furthermore, referring to Figure 1 and Figure 2 Distance sensors 8 and indicator lights 81 are installed at both the front and rear ends of the sliding base 1. The distance sensors 8 can be laser rangefinders, used to detect the distance between the sliding base 1 and obstacles in front and behind. Specifically, at the same end of the sliding base 1, the indicator light 81 is installed in the center, and a distance sensor 8 is installed on each side of the indicator light 81. The indicator light 81 at one end of the sliding base 1 is connected to all the distance sensors 8 at the other end of the sliding base 1 via signal lines or wireless communication. When the distance sensor 8 detects that the distance between one end of the sliding base 1 and the obstacle in front is less than a preset safe distance, the distance sensor 8 sends a signal to illuminate the indicator light 81 at the other end, reminding the personnel pushing the equipment to slow down, reducing the risk of collision caused by the inertia of the equipment, thereby improving the safety of transportation.

[0032] Reference Figure 1 and Figure 3An adjustable clamp 3 is fixedly connected to the end of the lifting component 2 away from the turntable 12. The adjustable clamp 3 has a cross-shaped clamping hole 30 in its center. The frame of the equipment module is embedded in the cross-shaped clamping hole 30 to achieve limiting and fixing. The lifting component 2 drives the equipment module to rise, so that the equipment module meets the height requirements for assembly. The retainer 4 is a sheet material with ductility, such as iron sheet or rubber sheet. The retainer 4 is detachably sleeved on the periphery of the turntable 12. The two ends of the retainer 4 extend to the two side walls of the sliding base 1. The retainer 4 is fastened to the sliding base 1, forming a state of semi-enclosing the sliding base 1. The inner wall of the retainer 4 is laterally rotatably mounted with guide wheels 41. When the retainer 4 is sleeved on the sliding base 1, the guide wheels 41 on both sides of the retainer 4 abut against the two sides of the equipment foundation, so that the sliding base 1 moves along the route of the equipment foundation, thereby making the transportation of curved sections more stable.

[0033] With the above scheme, when the equipment module needs to be transported, four sliding bases 1 are respectively placed at the four corners of the equipment module. The frame of the equipment module is locked in the cross-shaped locking holes and kept in place on the sliding bases 1, so that the sliding bases 1 can move forward along the equipment foundation. The guide wheels 41 assist in turning, thereby improving the stability of transportation. When passing through sections with large curves, the turntable 12 can create an angle difference between the sliding bases 1 and the entire equipment module, so that the sliding bases 1 at different positions can turn in accordance with the curvature of the equipment foundation. The entire equipment module can slowly adjust its direction of travel as it follows the sliding bases 1, further improving the stability of turning transportation. When it is necessary to fix the equipment module to fixed equipment with a height difference, the lifting component 2 can raise the equipment module to a height parallel to the equipment, which is convenient for combination and assembly.

[0034] In a preferred embodiment of this application, reference is made to Figure 1 and Figure 3 The adjustable clamp 3 includes a circular base 31 and four right-angled sector disks 32. The circular base 31 is fixedly mounted on the top of the lifting member 2 with screws, while the right-angled sector disks 32 are slidably connected to the circular base 31. The four right-angled sector disks 32 are spaced apart along the circumference of the circular base 31, with the right angles of the right-angled sector disks 32 facing the center of the circular base 31. The interval between the right-angled sides of any two right-angled sector disks 32 is a gap 33, and the four gaps 33 are interconnected to form a cross-shaped clamping hole 30. By driving the right-angled sector disks 32 to slide relative to the circular base 31, the width of the gaps 33 can be adjusted, thereby adjusting the width of the cross-shaped clamping hole 30 to adapt to the frames of different equipment modules.

[0035] Furthermore, referring to Figure 3A circular base 31 has a first groove on its top surface along a first direction, and a first screw 34 is rotatably connected within the first groove. The first screw 34 is driven by a micro motor. A right-angled sector disk 32 has a second groove on its bottom surface along a second direction, and a second screw 35 is rotatably connected within the second groove. The second screw 35 is driven by a micro motor. The first direction is perpendicular to the second direction, and the first screw 34 is perpendicular to the second screw 35. A linkage block 36 is mounted on the circular base 31. The bottom end of the linkage block 36 has a first threaded hole along the first direction, through which the first screw 34 passes and is threadedly connected to the linkage block 36. The top end of the linkage block 36 has a second threaded hole along the second direction, through which the second screw 35 passes and is threadedly connected to the linkage block 36. When the first screw 34 rotates, the linkage block 36 drives the right-angle sector disk 32 to move relative to the circular base 31 along the first direction, adjusting the width of the cross clamp hole 30 along the first direction. When the second screw 35 rotates, the right-angle sector disk 32 moves relative to the linkage block 36 along the second direction, adjusting the width of the cross clamp hole 30 along the second direction. When the first screw 34 and the second screw 35 rotate simultaneously, the width of the cross clamp hole 30 along the first and second directions is adjusted synchronously to meet the needs of equipment module frames of different shapes, thereby improving the adaptability of transportation vehicles.

[0036] In a preferred embodiment of this application, reference is made to Figure 2 and Figure 3 The retainer 4 has a centrally located hole 42. The inner wall of the hole 42 is fitted onto the circumference of the turntable 12. The diameter of the hole 42 is greater than or equal to the diameter of the turntable 12, thus allowing the retainer 4 to be detachably fitted onto the circumference of the turntable 12. In addition, two integrally formed limiting plates 5 extend downwards from the interior of the retainer 4. These two limiting plates 5 abut against both sides of the sliding base 1, restricting the circumferential rotation of the retainer 4 relative to the sliding base 1. This ensures that the sliding base 1 and the retainer 4 are aligned, enhancing the guiding function of the retainer 4, preventing the sliding base 1 from deviating from the equipment foundation, and improving the stability of transportation.

[0037] Furthermore, referring to Figure 2 A tenon 51 is vertically welded to the side of the limiting plate 5 near the sliding base 1. The tenon 51 can be elongated, cylindrical, or other irregularly shaped. In this embodiment, the tenon 51 is elongated. The side wall of the sliding base 1 has a mortise hole 13 vertically formed. The mortise hole 13 matches the shape of the tenon 51, and the tenon 51 is inserted into the mortise hole 13 to achieve a mortise and tenon connection. Through the cooperation of the tenon 51 and the mortise hole 13, the forward and backward sliding of the retainer 4 relative to the sliding base 1 can be restricted, so that the sliding base 1 moves synchronously with the retainer 4.

[0038] Furthermore, referring to Figure 2A tension spring 6 is bonded to the inner wall of the retainer 4, and the end of the tension spring 6 away from the inner wall of the retainer 4 is bonded to the limiting plate 5. Each time the retainer 4 is installed, the retainer 4 is fastened onto the sliding base 1, and then the tension spring 6 drives the inner wall of the retainer 4 to come close to the two side walls of the sliding base 1, so that the guide wheels 41 on the side walls of the retainer 4 are tightly abutted against the equipment foundation, which helps to improve the stability of transportation.

[0039] In a preferred embodiment of this application, reference is made to Figure 2 and Figure 4 The inner wall of the retainer 4 has a horizontally opening sliding hole 43, and a telescopic rod 7 is slidably embedded in the sliding hole 43. One end of the telescopic rod 7 extends towards the end close to the sliding base 1. The guide wheel 41 is horizontally rotatably mounted on the end of the telescopic rod 7. The other end of the telescopic rod 7 is slidably connected to the inner wall of the sliding hole 43. The end of the telescopic rod 7 is rotatably connected to a locking bolt 71. The distance between the guide wheel 41 and the equipment foundation below the sliding base 1 can be adjusted by the telescopic rod 7, and the distance can be locked by the locking bolt 71, so that the guide wheel 41 can be pressed against the roadbed guide rail of different widths, improving the adaptability of the transportation vehicle.

[0040] The experimental principle of this embodiment is as follows: When the equipment module needs to be transported, the first screw 34 and the second screw 35 drive the right-angle sector disk 32 to slide relative to the circular base 31, adjusting the width of the cross clamp hole 30 so that the frame of the equipment module can be embedded in the cross clamp hole 30 for fixed installation; then, the retainer 4 is sleeved on the sliding base 1, and the guide wheel 41 abuts against the equipment foundation. The retainer 4 guides the sliding base 1 to be transported along the transport path of the equipment foundation. During the transport process, the turntable 12 makes the angle of the retainer 4 and the overall equipment module match, increasing the flexibility of the transport vehicle, adapting to the corner requirements of curves, and improving the safety of turning; when transported to the end of the transport path for assembly, the lifting component 2 raises the equipment module to the height of the fixed equipment, replacing the step of laying the pad, which can effectively save time and improve transport efficiency.

Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
