[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0037] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a transport device, which includes: a fixed seat 10, a telescopic member 20 and a walking part 30. The fixed seat 10 is used to be fixed on the bottom of the article, and a transport hole 11 is provided on the fixed seat 10. The transport hole 11 extends in the horizontal direction, and the transport hole 11 is used to transport the article. The telescopic member 20 has a relatively arranged connecting end and a telescopic end, the connecting end is connected to the fixed seat 10, and the telescopic end can move in the vertical direction relative to the connecting end. The walking part 30 is arranged at the telescopic end, and the telescopic member 20 can drive the walking part 30 to move in the vertical direction. The walking part 30 has a relatively arranged supporting position and an avoidance position. When the walking part 30 is in the supporting position, the walking part 30 is lower than the bottom surface of the article, so that the article is supported and moved by the walking part 30; when the walking part 30 is in the avoidance position, the walking part 30 is higher than the transport hole 11 to avoid the transport hole 11, and the transport device can transport the article through the transport hole 11. In the present application, the X-axis and the Y-axis are located in a horizontal plane. Specifically, the X-axis extends along the length direction of the fixing base 10 , the Y-axis extends along the width direction of the fixing base 10 , and the Z-axis extends along the vertical direction of the fixing base 10 .

[0038] By applying the technical solution of the utility model, when the walking part 30 is in the supporting position, the walking part 30 will block the carrying hole 11, and the telescopic part 20 drives the walking part 30 to move in the vertical direction to below the bottom surface of the article, so as to support and move the article through the walking part 30; when the walking part 30 is in the avoiding position, the walking part 30 avoids the carrying hole 11, and the telescopic part 20 drives the walking part 30 to move in the vertical direction to above the carrying hole, and the article is carried through the carrying hole 11 in cooperation with other carrying equipment. In this way, when carrying large articles, there is no need to disassemble the articles, and switching the walking part can facilitate the movement and carrying of the entire article, which can adapt to different usage scenarios. The above structure greatly improves the carrying efficiency while saving manpower.

[0039] In the present application, there is no limitation on the structure of the telescopic member, and a telescopic structure such as an oil cylinder, a hydraulic cylinder or a pneumatic cylinder may be used.

[0040] Specifically, the transport device further includes a driving mechanism, which is drivingly connected to the telescopic end, and the driving mechanism can drive the telescopic end to move in the vertical direction relative to the connection end, thereby driving the walking part 30 to switch between the supporting position and the avoidance position. In this way, the telescopic end is controlled by the driving mechanism, which improves the convenience and controllability of the operation and further saves manpower.

[0041] The telescopic member 20 includes a sleeve 21 and a telescopic cylinder 22. The sleeve 21 is connected to the fixing seat 10 and is sleeved on the outer periphery of the telescopic cylinder 22. The telescopic cylinder 22 can move in the vertical direction relative to the sleeve 21. The top of the telescopic cylinder 22 is located in the sleeve 21, and the bottom of the telescopic cylinder 22 forms a telescopic end. The above arrangement has a simple structure, is easy to disassemble and repair, and is convenient for processing and manufacturing. It can be processed and customized according to the objects of different specifications, which improves the flexibility and applicability of the device.

[0042] Furthermore, an end cover 211 is provided on the top of the sleeve 21 , and the end cover 211 is fixedly connected to the sleeve 21 via a buckle.

[0043] In the present application, the driving mechanism includes a screw rod 41, which is rotatably arranged in the sleeve 21, and the telescopic cylinder 22 is threadedly connected to the screw rod 41. There is a rotation-stopping structure between the sleeve 21 and the telescopic cylinder 22 to limit the rotation of the telescopic cylinder 22 relative to the sleeve 21, and the screw rod 41 drives the telescopic cylinder 22 to move in the vertical direction relative to the sleeve 21. Through the above arrangement, the rotation of the screw rod 41 can drive the telescopic cylinder 22 to move in the vertical direction relative to the sleeve 21, thereby completing the switching of the walking part 30 between the avoidance position and the support position. The threaded connection can adjust the telescopic length of the telescopic cylinder 22 in a gradient, and the controllability of the single adjustment accuracy is high, the structure is simple, and the operation is convenient. By changing the thread size of the screw rod 41, fine adjustments of different gradients can be made to meet the handling needs of items of different sizes.

[0044] Specifically, the telescopic cylinder 22 is provided with a threaded structure only on the inner wall of the top, and the bottom of the screw rod 41 is not provided with a threaded structure. In this way, the bottom of the screw rod 41 can serve as a limiting structure to prevent the telescopic cylinder 22 from falling off the outer periphery of the screw rod 41. At the same time, the weight of the device can be reduced, making it easier to store and carry.

[0045] The anti-rotation structure can prevent the telescopic cylinder 22 and the sleeve 21 from rotating relative to each other, that is, prevent the telescopic cylinder 22 from rotating together with the screw rod 41, and ensure that the telescopic cylinder 22 can be displaced in the vertical direction relative to the sleeve 21. In other embodiments of the present application, the screw rod 41 can also be set to be non-rotatable, and the telescopic cylinder 22 can rotate relative to the screw rod 41, and no anti-rotation structure is set between the telescopic cylinder 22 and the sleeve 21, so that the telescopic cylinder 22 can still be displaced in the vertical direction relative to the sleeve 21.

[0046] like Figures 2 to 4 As shown, the anti-rotation structure includes a groove 51 and a protrusion 52. The protrusion 52 is arranged on the inner side wall of the sleeve 21 along the extension direction of the sleeve 21, and the groove 51 is arranged on the outer side wall of the telescopic cylinder 22. The protrusion 52 cooperates with the groove 51 to limit the rotation of the telescopic cylinder 22 relative to the sleeve 21. Through the above arrangement, the telescopic cylinder 22 can be smoothly moved along the extension direction of the screw rod 41, avoiding the rotation of the telescopic cylinder 22 relative to the sleeve 21 to affect the movement effect of the telescopic cylinder 22 in the vertical direction of the sleeve 21, and through the cooperation of the groove 51 and the protrusion 52, the sleeve 21 and the telescopic cylinder 22 can be quickly positioned when assembled, thereby improving the installation efficiency of the device. At the same time, the above device has a simple structure and is easy to process and produce.

[0047] In other embodiments of the present application, the groove 51 may be provided on the inner wall of the sleeve 21 , and the protrusion 52 may be provided on the outer wall of the telescopic tube 22 .

[0048] like Figure 2 As shown, the driving mechanism also includes a handle 42 and a transmission mechanism. The handle 42 is rotatably arranged on the sleeve 21. The handle 42 is drivingly connected to one end of the transmission mechanism, and the other end of the transmission mechanism is drivingly connected to the screw 41. The handle 42 drives the screw 41 to rotate through the transmission mechanism. Through the above arrangement, the screw 41 can be driven to rotate by rotating the handle 42, thereby driving the telescopic cylinder 22 to move in the vertical direction relative to the sleeve 21, thereby driving the walking part to switch between the supporting position and the avoidance position to carry the items. The structure is simple, which greatly improves the convenience of using the carrying device.

[0049] In other embodiments of the present application, the handle 42 may also be configured as an electric motor, a motor or other power source to provide driving force for the driving mechanism.

[0050] In the present application, the transmission mechanism includes a first transmission gear 61 and a second transmission gear 62, the first transmission gear 61 is fixedly connected to the handle 42, and the axis of the first transmission gear 61 coincides with the rotation axis of the handle 42, the second transmission gear 62 is fixedly connected to one end of the screw 41, the axis of the second transmission gear 62 coincides with the axis of the screw 41, and the first transmission gear 61 and the second transmission gear 62 are meshed with each other. In the above arrangement, the first transmission gear 61 and the second transmission gear 62 are perpendicular to each other, and can limit each other to avoid displacement of the handle 42 in the horizontal direction and displacement of the screw 41 in the vertical direction, thereby ensuring the stable operation of the device. When it is necessary to switch the state of the walking part 30, the handle 42 is rotated to drive the first transmission gear 61 to rotate, and then drive the second transmission gear 62 to rotate, so as to drive the screw 41 to rotate, thereby driving the telescopic cylinder 22 to move in the vertical direction relative to the sleeve 21. In this design, the transmission direction of the force is changed through a simple structure, the device structure is simplified, and the structural volume of the device is reduced.

[0051] like Figure 2 , Figures 5 to 7 As shown, the first transmission gear 61 and the second transmission gear 62 are provided with shaft mounting holes 63, respectively, and the shaft mounting holes 63 are used for the handle 42 and the screw rod 41 to penetrate the first transmission gear 61 and the second transmission gear 62, respectively. The second transmission gear 62 and the screw rod 41 are provided with a first limiting hole 64 and a second limiting hole 66, respectively, and the first transmission gear 61 and the handle 42 are provided with a third limiting hole and a fourth limiting hole 67, respectively. The transmission mechanism also includes a plurality of limiting rods 65, and the limiting rods 65 cooperate with the above-mentioned limiting holes to fix the relative positions between the first transmission gear 61 and the handle 42, and between the second transmission gear 62 and the screw rod 41, so as to prevent the first transmission gear 61 and the handle 42, and between the second transmission gear 62 and the screw rod 41 from rotating relative to each other.

[0052] Specifically, a mounting hole arranged in the horizontal direction is also provided on the sleeve 21 for the handle 42 to pass through, and a bushing 421 is also fixedly provided on the outer circumference of the portion of the handle 42 passing through the sleeve 21 to limit the position of the handle 42 in the sleeve 21 to ensure smooth transmission of the driving force.

[0053] like Figure 1As shown, a limiting step 23 is provided on the inner side wall of the sleeve 21, and the limiting step 23 has a through hole. The screw rod 41 is rotatably provided on the limiting step 23, and one end of the screw rod 41 passes through the through hole and is connected to the telescopic cylinder 22. The limiting step 23 can limit the displacement of the screw rod 41 in the vertical direction in the sleeve 21. The second transmission gear 62 is located on the limiting step 23, and the diameter of the second transmission gear 62 is larger than the diameter of the through hole. The position of the screw rod 41 in the vertical direction is limited and fixed by the second transmission gear 62 and the limiting step 23, thereby ensuring the adjustment accuracy of the telescopic cylinder 22 in the vertical direction.

[0054] In this embodiment, a protrusion is provided on the limiting step 23, and a corresponding socket is provided on the sleeve 21. The protrusion and the socket are plugged into each other to fix the position of the limiting step 23 in the sleeve 21, thereby controlling the displacement of the screw rod 41 in the vertical direction in the sleeve 21.

[0055] In other embodiments of the present application, the position of the limiting step 23 in the sleeve 21 may also be fixed by fasteners or other structures.

[0056] The telescopic member 20 is connected to the second mounting member 13 via a sleeve 21 , a connecting block 70 is welded to the outside of the sleeve 21 , and the connecting block 70 is fixedly connected to the second mounting member 13 via a fastener.

[0057] like Figure 8 As shown, the fixing base 10 includes a first mounting member 12 and a second mounting member 13, the first mounting member 12 and the second mounting member 13 have an angle, the handling device is fixedly connected to the article through the first mounting member 12, and the second mounting member 13 is fixedly connected to the telescopic member 20. Through the above arrangement, the stability of the fixing base 10 can be ensured, and the handling efficiency of the handling device can be ensured.

[0058] Specifically, the second mounting member 13 is vertically arranged on the first mounting member 12, and the second mounting member 13 is located at one end of the first mounting member 12, the carrying hole 11 is arranged at the bottom end of the second mounting member 13, and the telescopic member 20 is connected to the top end of the second mounting member 13 and is located on the side of the second mounting member 13 away from the first mounting member 12. Through the above arrangement, the first mounting member 12 and the second mounting member 13 are prevented from interfering with the telescopic member 20, and the structural strength of the fixing seat 10 is further improved.

[0059] In the present application, the first mounting member 12 and the second mounting member 13 are respectively composed of a frame and a mounting plate, the mounting plate is fixedly connected to the frame, and the fixing seat 10 is fixedly connected to the object and the telescopic member through the mounting plate, so that the overall weight of the device can be reduced and the device can be made lighter. There are also reinforcing ribs between the frames to improve the structural stability of the fixing seat 10.

[0060] like Figure 2 and Figure 4 As shown, the walking part 30 includes a roller, and the bottom of the telescopic cylinder 22 is provided with a mounting surface 221, and the walking part 30 is fixedly connected to the telescopic member 20 by a fastener cooperating with the mounting surface 221. In this way, the contact area between the telescopic member 20 and the walking part 30 is increased, and the stability of the connection is improved.

[0061] Specifically, when the transport device provided by the present application is used to transport an item, multiple transport devices can be used to cooperate with each other to complete the transport work according to the size of the item. In this embodiment, an open millimeter wave security inspection device is used as an example. Fig. 9 As shown, when the open millimeter wave security scanner is transported to the site and needs to be installed and constructed: after removing the outer packaging, multiple handling devices are respectively installed on the base of the open millimeter wave security scanner. At this time, the walking part 30 is in the avoidance position, and the worker can drive a forklift to fork the fork arm into the handling hole 11 on the fixed seat 10, and lift it upward to fork up the whole machine and transport it to the designated installation location. After the placement is completed, the handling device can be removed from the base of the open millimeter wave security scanner by loosening the fastener screws.

[0062] like Fig.10 As shown, when the open millimeter wave security scanner needs to be moved a short distance: after installing multiple transport devices on the base of the open millimeter wave security scanner respectively, shake the handle 42 to drive the screw rod 41 to rotate through the thread to move the telescopic cylinder 22 downward relative to the sleeve 21, so as to lift the entire open millimeter wave security scanner upward. When the entire machine is lifted off the ground, the movement can be achieved by pushing the door body. After the open millimeter wave security scanner is moved to the destination, turn the handle 42 to drive the telescopic cylinder 22 upward through the screw rod 41, so that the entire machine can fall back downward. When the rollers of all the transport devices are off the ground, the open millimeter wave security scanner has been firmly placed on the ground. After the placement is completed, the transport device is removed from the base of the open millimeter wave security scanner by loosening the fastener screws to complete the mobile installation of the entire machine.
