[0029] The axial direction of the mounting shafts 10 and the conveying rollers 11 is perpendicular to the side plates 14, and the top surface of the conveying rollers 11 is slightly higher than the top surface of the chassis 1; when the large equipment is placed on the conveying rollers 11, the large equipment is pushed to make the conveying rollers 11 rotate on the mounting shafts 10 and drive the large equipment to move, so that the large equipment is easily moved from the loading and unloading end of the chassis 1 to the direction of the baffle 13.

[0030] Preferably, the mounting shafts 10 and the conveying rollers 11 can adopt the conveying rollers in the prior art, and the number of the mounting shafts 10 and the conveying rollers 11 is adaptively adjusted according to the size of the chassis 1, so as to basically cover or partially cover the placing area of the chassis 1; the conveying rollers are the commonly used auxiliary transportation mechanism in the field, and the specific structure and working principle thereof will not be described herein.

[0031] Please see the accompanying drawings Figure 1 and the accompanying drawings Figure 2 , the loading and unloading assembly further comprises a movable limiting mechanism; the loading and unloading end of the chassis 1 is formed with an extension groove 3 which is in communication with the groove, and the movable limiting mechanism is movably embedded in the extension groove 3; the movable limiting mechanism can abut against the bottom of the large equipment to position the large equipment on the chassis 1.

[0032] The movable limiting mechanism is used to assist the large equipment to move from the loading and unloading end of the chassis 1 to the chassis 1, so as to reduce the labor intensity of the operator. Meanwhile, the movable limiting mechanism is used to provide a certain abutting and limiting function for the large equipment, so as to further prevent the large equipment from being overturned under the action of external force.

[0033] Please see the accompanying drawings Figure 2 , the movable limiting mechanism comprises clamping jacks 4, trapezoidal top blocks 5, connecting plates 7 and jacking springs 8; the lower end of the clamping jacks 4 is movably penetrated through the chassis 1 and is perpendicularly fixedly connected with the connecting plates 7, and the upper end of the clamping jacks 4 is perpendicularly fixedly connected with the bottom surface of the trapezoidal top blocks 5; the jacking springs 8 are sleeved on the clamping jacks 4, the lower end of the jacking springs 8 is tightly abutted against the bottom surface of the extension groove 3, the upper end of the jacking springs 8 is tightly abutted against the bottom surface of the trapezoidal top blocks 5, so that the trapezoidal top blocks 5 are movably embedded in the extension groove 3 through the jacking springs 8; when the top surface of the trapezoidal top blocks 5 is higher than the top surface of the chassis 1, the top surface of the trapezoidal top blocks 5 is flush with the top surface of the chassis 1, and the bottom surface of the connecting plates 7 is higher than or equal to the bottom surface of the universal wheels 2.

[0034] Preferably, when the top surface of the connecting plate 7 is attached to the bottom surface of the chassis 1, the top surface of the trapezoidal top block 5 is higher than the top surface of the conveying drum 11, so that the large equipment can be provided with abutting and limiting by the protruding trapezoidal top block 5, and the stability and safety of the large equipment can be improved.

[0035] The length of the trapezoidal top block 5 can be adaptively set according to the width of the large equipment, and preferably, the length of the trapezoidal top block 5 is slightly larger than the width of the large equipment. The operator only needs to slightly incline the large equipment, so that one end of the bottom of the large equipment can be placed on the trapezoidal top block 5, and the large equipment is pushed onto the chassis 1 by the trapezoidal top block 5. At this time, the trapezoidal top block 5 moves downward under the action of the gravity of the large equipment, and the lifting spring 8 is compressed to store energy; after the large equipment passes through the trapezoidal top block 5 and is completely moved onto the conveying drum 11, the lifting spring 8 can lift the trapezoidal top block 5 to realize the protruding abutting and limiting function.

[0036] The clamping top rod 4 and the lifting spring 8 are arranged in groups, and preferably, three groups of clamping top rods 4 and lifting springs 8 can be arranged, or the number of groups can be increased or decreased according to the actual load demand. The connecting plate 7 is used to connect the clamping top rods 4 into a whole, and when the connecting plate 7 is attached to the bottom surface of the chassis 1, the upward movement of the trapezoidal top block 5 is limited. When the top surface of the trapezoidal top block 5 is flush with the top surface of the chassis 1, the connecting plate 7 is lowered to be not lower than the bottom surface of the universal wheel 2, so that the connecting plate 7 can be prevented from being damaged by colliding with the ground.

[0037] Please refer to the accompanying drawings Figure 2 , the top surface of the trapezoidal top block 5 is a slope structure, and the slope structure extends outward from the loading and unloading end of the chassis 1 and gradually decreases in thickness; one end of the trapezoidal top block 5 close to the groove is a vertical plane, so that the large equipment is positioned between the vertical plane and the baffle 13.

[0038] The slope structure can provide a guiding function, so that the operator can more easily push the large equipment onto the chassis 1. The vertical plane can provide an abutting and limiting function, and when the trapezoidal top block 5 protrudes upward, it can provide abutting and limiting for the large equipment on the chassis 1, so that the large equipment can be prevented from sliding on the conveying drum 11 or tilting on the chassis 1.

[0039] Please refer to the accompanying drawings Figure 2 , the two side surfaces of the trapezoidal top block 5 form a limiting protrusion 6, and a vertically arranged limiting sliding groove 9 is formed on the two side inner walls of the extending groove 3, and the limiting protrusion 6 is slidably arranged in the limiting sliding groove 9.

[0040] The limiting protrusion 6 moves up and down synchronously with the trapezoidal top block 5, and the limiting sliding groove 9 provides sliding limiting and guiding for the limiting protrusion 6, so that the vertical lifting stability of the trapezoidal top block 5 is improved.

[0041] Please refer to the accompanying drawings Figure 1 , the accompanyingFigure 3 and attached Figure 4 The both sides of the loading and unloading end of the base frame 1 and the top of the baffle 13 are formed with vertical positioning insertion holes 12, and the four corners of the fixed frame 15 are formed with positioning clamping columns 1501, which are respectively inserted into the four positioning insertion holes 12, so that the fixed frame 15 can be detachably mounted on the base frame 1 and the baffle 13.

[0042] Since the baffle 13 is higher than the base frame 1, preferably, the open end of the U-shaped fixed frame 15 is arranged on the top of the baffle 13, and the closed end of the U-shaped fixed frame 15 is provided with a vertical rod with a corresponding height, so that the U-shaped fixed frame 15 can be horizontally arranged on the base frame 1 and the baffle 13, and better lateral protection effect is achieved.

[0043] The four positioning clamping columns 1501 are respectively located at the bottom of the vertical rod of the open end and the closed end of the fixed frame 15, and the vertical insertion of the four positioning clamping columns 1501 and the four positioning insertion holes 12 makes the disassembly and assembly of the fixed frame 15 convenient and fast, and the insertion stability is high and the horizontal movement is avoided.

[0044] Please refer to the attached Figure 1 , attached Figure 3 and attached Figure 4 The top of the baffle 13 is formed with mounting blocks 16, and the inner side wall of the open end of the fixed frame 15 is formed with fixed insertion holes 1502; one end of the fixed insertion rod 19 is slidably arranged in the mounting block 16, and the other end of the fixed insertion rod 19 can extend out of the mounting block 16 and be movably inserted into the fixed insertion hole 1502, and the axial direction of the fixed insertion rod 19 is perpendicular to the axial direction of the positioning clamping column 1501, so that the fixed frame 15 can be detachably connected to the baffle 13.

[0045] The insertion of the fixed insertion rod 19 and the positioning clamping column 1501 can further connect the fixed frame 15 and the baffle 13, and the fixed insertion rod 19 and the positioning clamping column 1501 provide bidirectional limiting for the fixed frame 15, so that the installation of the fixed frame 15 is more firm and reliable, and the lateral protection effect is further improved.

[0046] Please refer to the attached Figure 3 The mounting block 16 is formed with a mounting groove 17 and a sliding groove 18 at intervals, and the fixed insertion rod 19 penetrates the mounting groove 17 and the sliding groove 18; the fixed insertion rod 19 is formed with a push plate 22, which is slidably arranged in the sliding groove 18 and extends upward above the mounting block 16; the fixed insertion rod 19 is sleeved with a fixed spring 21, which is located in the mounting groove 17, one end of the fixed spring 21 is fixed to the inner wall of the end of the mounting groove 17 away from the fixed frame 15, the other end of the fixed spring 21 is fixedly arranged on the fixed insertion rod 19 through a limiting plate 20, and the limiting plate 20 can abut against the inner wall of the end of the mounting groove 17 close to the fixed frame 15.

[0047] The lever 22 is fixedly connected to the fixed rod 19 and can be used to manually slide the fixed rod 19 laterally. When the fixed rod 19 moves into the retractable mounting block 16, it facilitates the insertion of the positioning pin 1501 of the fixing bracket 15 into the positioning hole 12 on the baffle 13. At this time, the fixing spring 21 is compressed and stores force. After the insertion is completed, the lever 22 is released, and the fixed rod 19 is popped out under the action of the fixing spring 21, so that the end of the fixed rod 19 extends out of the mounting block 16 and is inserted into the fixing hole 1502.

[0048] The limiting plate 20 can move synchronously with the fixed rod 19 under the elastic force of the fixed spring 21, and move to abut against the inner wall of the mounting groove 17 near the fixed frame 15, thereby limiting the range of movement of the fixed rod 19.

[0049] Please see the appendix Figure 1 The end of the pair of side plates 14 away from the baffle 13 is inclined, and the inclined structure extends obliquely downward toward the loading and unloading end of the base frame 1.

[0050] One end of each pair of side plates 14, away from the baffle 13, extends only to the middle of the side end of the base frame 1 and has a sloping structure, which can minimize the risk of collision between the large equipment and the side plates 14 when it is transported onto the base frame 1. After the large equipment is transported onto the base frame 1, the fixing frame 15 surrounds and fills the unprotected parts of the side plates 14 and the baffle 13, thus ensuring both the safety of loading and unloading the large equipment and the stability of its transport.

[0051] Please see the appendix Figure 1 To be continued Figure 4 The method of use and working principle of this utility model are as follows:

[0052] The present invention can be moved to the side of large medical testing equipment or other large equipment by means of the universal wheels 2. The operator can tilt the large equipment slightly and place the bottom of the large equipment on the top surface of the trapezoidal top block 5. Since the top surface of the trapezoidal top block 5 is a sloping structure, it can provide sliding guidance for the large equipment. By pushing the large equipment along the sloping structure, the large equipment can be moved to the base frame 1 with relatively little effort.

[0053] Meanwhile, due to the rotation of the conveyor roller 11, the sliding friction of the large equipment ground is converted into rolling friction, which makes it easier for operators to move the large equipment onto the base frame 1, and can minimize the problem of the large equipment sliding on the base frame 1 and causing wear on the bottom surface.

[0054] Depending on the number and size of the large equipment, a base frame 1 of appropriate size can be used to transport one or more large pieces of equipment. Multiple large pieces of equipment are sequentially moved onto the base frame 1 using the method described above; the handling process will not be described in detail here.

[0055] Through the U-shaped structure of the baffle 13 and the pair of side plates 14, the three sides are wrapped on the outer wall of the one or more large equipment on the chassis 1, and lateral protection is provided for the large equipment. The baffle 13 and the pair of side plates 14 are arranged relatively far away from the loading and unloading end, and the end of the pair of side plates 14 close to the loading and unloading end is in a beveled structure, which can maximize the collision between the large equipment and the pair of side plates 14 during loading and unloading.

[0056] During the process of moving the large equipment to the chassis 1, the trapezoidal top block 5 is pressed to move downward, and the lifting spring 8 is compressed to store energy; after the large equipment is moved to the chassis 1, the trapezoidal top block 5 is moved upward to reset under the elastic force of the lifting spring 8, and the top surface of the trapezoidal top block 5 is moved to be higher than the chassis 1, so that the vertical plane of the trapezoidal top block 5 can be abutted on the large equipment, thereby playing a limiting role on the large equipment. When the large equipment is unloaded, only the trapezoidal top block 5 needs to be pressed.

[0057] Finally, the fixed frame 15 is inserted and connected to the chassis 1 and the baffle 13 through the four positioning clamping columns 1501 via the positioning insertion hole 12, the open end of the fixed frame 15 is located on the baffle 13, and the closed end of the fixed frame 15 is located at the loading and unloading end of the chassis 1, so that the baffle 13, the pair of side plates 14 and the fixed frame 15 are connected to form a circumferential lateral protection structure and provide circumferential protection for the large equipment.

[0058] When the fixed frame 15 is installed, the push plate 22 is pushed to move the fixed insertion rod 19 away from the fixed frame 15 and retract into the mounting block 16, and the fixed spring 21 is compressed to store energy, so as to avoid interference with the insertion and installation of the fixed frame 15. After the fixed frame 15 is inserted and installed, the push plate 22 is released, the fixed insertion rod 19 is reset in the direction of the fixed frame 15 under the elastic force of the fixed spring 21, and the end of the fixed insertion rod 19 extends out of the mounting block 16 and is inserted into the fixed insertion hole 1502. The vertical fixed insertion rod 19 and the positioning clamping column 1501 are used to bidirectionally limit the fixed frame 15, so as to ensure the reliable installation of the fixed frame 15 and provide effective lateral protection effect.

[0059] The above is only a preferred embodiment of the present application, and is not used to limit the protection scope of the present application, therefore, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
