DETAILED DESCRIPTION

[0023] To make the technical solutions and advantages of the present invention more clear, the present invention and its beneficial effects will be described in further detail below in conjunction with specific implementation methods and accompanying drawings, but the implementation methods of the present invention are not limited thereto.

[0024] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art. Machinery, parts and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.

[0026] The following is combined with Figure 1-4 , further details of this application are given.

[0027] The present application provides a transport tool with adaptive height, which adopts the following technical solution:

[0028] Reference Figure 1 and Figure 2 The transport tool includes a sliding base 1, a lifting member 2, an adjustable clamp 3 and a retaining frame 4. The sliding base 1 serves as a sliding base, and the sliding base 1 is placed on the equipment foundation to slide along the transport path. Furthermore, the bottom surface of the sliding base 1 is rotatably connected with rollers 11, and the number of rollers 11 is an even number, and the even number of rollers 11 are arranged side by side on the sliding base 1. In this embodiment, 8 rollers 11 are rotatably installed on the bottom surface of the sliding base 1, which are arranged in pairs, and 4 groups of rollers 11 are rotatably connected to the bottom surface of the sliding base 1. Compared with other rollers, the rollers 11 can increase the contact area between the sliding base 1 and the roadbed guide rail, and evenly distribute the load of the sliding base 1 to the ground, thereby improving the bearing capacity of the sliding base 1; in addition, the rollers 11 distributed side by side can make the sliding base 1 on the equipment foundation slide more smoothly through load balancing on the left and right sides.

[0029] Reference Figure 1 and Figure 3The top surface of the sliding base 1 is embedded with a turntable 12, which rotates around its own center of circle, and can adjust the direction of the object carried on the sliding base 1 to meet different turning requirements. The lifting member 2 is fixedly installed on the turntable 12, and each lifting member 2 is installed with a height sensor (not shown in the figure), which can monitor the distance between the top surface of the lifting member and the ground, and transmit signals to the chip installed on the lifting member 2. Through the chip of the lifting member 2, the lifting member 2 is controlled to rise or fall. In the actual application process, communication is established between the lifting members 2 installed in different directions of the equipment module, and each lifting member is adaptively adjusted according to the unevenness of the local ground, and the top surfaces of all the lifting members 2 are always at the same level, so that the equipment module is always on the same level, thereby adapting to complex road conditions and improving the flexibility and stability of the transportation tool.

[0030] Furthermore, the lifting member 2 is a multi-stage hydraulic jack, which includes at least three-stage jack rods 21. The height of each stage of the jack rods 21 is not more than 15 cm. In this embodiment, the height of each stage of the jack rods 21 is 10 cm. The lifting member 2 can be folded into one layer, occupying only 10 cm of height space, reducing the floor space and facilitating transportation by means of transportation, and can also be unfolded and extended to a height of 30 cm to meet the height requirements of the assembly environment.

[0031] Further, refer to Figure 1 and Figure 2 The front and rear ends of the sliding base 1 are both equipped with distance measuring sensors 8 and signal lights 81. The distance measuring sensor 8 can be a laser rangefinder, which is used to detect the distance between the sliding base 1 and the obstacles in the front and rear. Specifically, at the same end of the sliding base 1, the signal light 81 is installed in the center, and a distance measuring sensor 8 is installed on each side of the signal light 81. The indicator light 81 at one end of the sliding base 1 is connected to all the distance measuring sensors 8 at the other end of the sliding base 1 through a signal line or wireless communication. When the distance measuring sensor 8 detects that the distance between one end of the sliding base 1 and the obstacle in front is less than the preset safety distance, the distance measuring sensor 8 sends a signal to light up the signal light 81 at the other end, reminding the staff pushing the equipment at the rear to slow down, reduce the risk of collision caused by the inertia of the equipment, and thus improve the safety of transportation.

[0032] Reference Figure 1 and Figure 3The adjustable clamp 3 is fixedly connected to the end of the lifting member 2 away from the turntable 12. A cross clamp hole 30 is opened in the center of the adjustable clamp 3. The frame of the equipment module is embedded in the cross clamp hole 30 to achieve limited fixation. The equipment module is driven to rise by the lifting member 2 so that the equipment module meets the height requirements of assembly. The retaining frame 4 is a sheet material with ductility, such as an iron sheet, a rubber sheet, etc. The retaining frame 4 is detachably sleeved on the peripheral side of the turntable 12. The two ends of the retaining frame 4 extend to the two side walls of the sliding base 1. The retaining frame 4 is buckled on the sliding base 1 to form a state of half-wrapping the sliding base 1. A guide wheel 41 is installed on the inner wall of the retaining frame 4 for transverse rotation. When the retaining frame 4 is sleeved and installed on the sliding base 1, the guide wheels 41 on both sides of the retaining frame 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 curved transportation more stable.

[0033] Through the above scheme, when it is necessary to transport the equipment module, the four sliding bases 1 are respectively placed at the four corners of the equipment module, and the frame of the equipment module is clamped in the limit position in the cross clamping hole to keep it relatively sleeved on the sliding base 1, so that the sliding base 1 moves along the equipment foundation, and the guide wheel 41 assists in turning, thereby improving the stability of transportation; when passing through a section with a large curvature, the turntable 12 can be used to create an angle difference between the sliding base 1 and the equipment module as a whole, so that the front and rear different sliding bases 1 follow the curvature of the equipment foundation to turn, and the equipment module as a whole slowly adjusts the direction of travel while following the sliding base 1, further improving the stability of turning transportation; when it is necessary to fix the equipment module to a fixed device with a height difference, the equipment module is raised to a height parallel to the equipment through the jacking member 2, which is convenient for combined matching and assembly.

[0034] In the preferred embodiment of the present application, refer to Figure 1 and Figure 3 The adjustable clamp 3 includes a circular chassis 31 and four right-angled sector disks 32. The circular chassis 31 is fixedly installed on the top of the jacking member 2 by screws, and the right-angled sector disks 32 are slidably connected to the circular chassis 31. The four right-angled sector disks 32 are spaced apart along the circumferential direction of the circular chassis 31, and the right angles of the right-angled sector disks 32 face the center of the circular chassis 31. The interval between the right-angled sides of the two right-angled sector disks 32 is a slit 33, and the four slits 33 are interconnected to form a cross clamp hole 30. By driving the right-angled sector disks 32 to slide relative to the circular chassis 31, the width of the slit 33 can be adjusted, thereby adjusting the width of the cross clamp hole 30 to adapt to the framework of different equipment modules.

[0035] Further, refer to Figure 3The top surface of the circular chassis 31 is provided with a first groove along the first direction, and a first screw 34 is rotatably connected in the first groove, and the first screw 34 is driven by a micro motor; the bottom surface of the right-angled sector disk 32 is provided with a second groove along the second direction, and a second screw 35 is rotatably connected in the second groove, and 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 installed on the circular chassis 31, and a first threaded hole is provided at the bottom end of the linkage block 36 along the first direction, and the first screw 34 passes through the first threaded hole and is threadedly connected to the linkage block 36; a second threaded hole is provided at the top end of the linkage block 36 along the second direction, and the second screw 35 passes through the second threaded hole and is threadedly connected to the linkage block 36. When the first screw 34 rotates, the linkage block 36 drives the right-angled sector disk 32 to move along the first direction relative to the circular chassis 31, and adjusts the width of the cross-clamp hole 30 along the first direction. When the second screw 35 rotates, the right-angled sector disk 32 moves along the second direction relative to the linkage block 36, and adjusts the width of the cross-clamp hole 30 along the second direction. When the first screw 34 and the second screw 35 rotate at the same time, the widths of the cross-clamp hole 30 in the first direction and the second direction are adjusted synchronously to meet the needs of equipment module frames of different shapes, thereby improving the adaptability of transportation tools.

[0036] In the preferred embodiment of the present application, refer to Figure 2 and Figure 3 A sleeve hole 42 is provided at the center of the retainer 4, and the inner wall of the sleeve hole 42 is sleeved on the circumference of the turntable 12. The diameter of the sleeve hole 42 is greater than or equal to the diameter of the turntable 12, so that the retainer 4 can be detachably sleeved and installed on the circumference of the turntable 12. In addition, two limit plates 5 are integrally formed in the interior of the retainer 4 extending downward, and the two limit plates 5 are respectively abutted on both sides of the sliding base 1. The two limit plates 5 can limit the circumferential rotation of the retainer 4 relative to the sliding base 1, so that the guidance of the sliding base 1 and the retainer 4 are consistent, thereby 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] Further, refer to Figure 2 , a tenon column 51 is vertically welded on one side of the limit plate 5 close to the sliding base 1. The tenon column 51 can be in the shape of a strip, a cylinder or other special shapes. In this embodiment, the tenon column 51 is in the shape of a strip, and a tenon hole 13 is vertically opened on the side wall of the sliding base 1. The tenon hole 13 matches the shape of the tenon column 51, and the tenon column 51 is inserted into the tenon hole 13 to realize the mortise and tenon connection. Through the cooperation of the tenon column 51 and the tenon hole 13, the forward and backward sliding of the retaining frame 4 relative to the sliding base 1 can be limited, so that the sliding base 1 moves synchronously with the retaining frame 4.

[0038] Further, refer to Figure 2The inner wall of the holder 4 is bonded with a tension spring 6, and one end of the tension spring 6 away from the inner wall of the holder 4 is bonded to the limit plate 5. Each time the holder 4 is installed, the holder 4 is buckled and sleeved on the sliding base 1, and then the inner wall of the holder 4 is driven by the tension spring 6 to be close to the two side walls of the sliding base 1, so that the guide wheel 41 of the side wall of the holder 4 is closely abutted against the equipment foundation, which is conducive to improving the stability of transportation.

[0039] In the preferred embodiment of the present application, refer to Figure 2 and Figure 4 A sliding hole 43 is horizontally opened on the inner wall of the retaining frame 4, and a telescopic rod 7 is slidably embedded in the sliding hole 43. One end of the telescopic rod 7 extends toward one end close to the sliding base 1. The guide wheel 41 is rotatably installed at 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 with a tightening bolt 71. The distance between the guide wheel 41 and the equipment foundation under the sliding base 1 can be adjusted through the telescopic rod 7, and the distance is locked by the tightening bolt 71, so that the guide wheel 41 can be tightened against roadbed guide rails of different widths, thereby improving the adaptability of the transportation tool.

[0040] The experimental principle of the embodiment of the present application is as follows: when the equipment module needs to be transported, the first screw 34 and the second screw 35 can drive the right-angle fan-shaped disk 32 to slide relative to the circular chassis 31, and adjust 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 and fixedly installed; then the retaining frame 4 is sleeved on the sliding base 1, and the guide wheel 41 abuts against the equipment foundation. The retaining frame 4 guides the sliding base 1 to be transported along the conveying path of the equipment foundation. During the transportation process, the turntable 12 is used to adapt the angle of the retaining frame 4 to the overall angle of the equipment module, thereby increasing the flexibility of the transportation tool, adapting to the turning angle requirements of the curve, and facilitating improving the safety of turning; when transported to the end of the conveying path for assembly, the equipment module is raised to the height of the fixed equipment by the jacking member 2, replacing the step of laying the pad, which can effectively save labor hours and improve transportation efficiency.

Therefore, the present invention is not limited to the above specific embodiment, and any obvious improvement, replacement or modification made by those skilled in the art on the basis of the present invention belongs to the protection scope of the present invention.
