Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment; more specifically, it relates to a mobile operating frame. Background Art

[0002] With the continuous development of society and the continuous improvement of technology level, mobile operating frames are often used in modern construction processes. A mobile operating frame is a device specifically designed for construction and construction sites, which is used to improve the safety, efficiency and convenience of construction. Such frames are usually used to support workers for working at heights, placing tools and materials, etc.

[0003] Currently, during the use of mobile operating frames in the prior art, most mobile operating frames are installed with universal wheels at the bottom for moving the equipment. Although universal wheels generally have brake pads, due to the small contact area between the universal wheels and the ground, and workers are inevitably shaken during use, the operating frame may still shake or move during use; and some existing operating frames are generally assembled by various components, making the structure of the equipment relatively scattered, and it is time-consuming and laborious to build or disassemble. Therefore, there is an urgent need for a mobile operating frame to solve the above problems. Summary of the Utility Model

[0011] Preferably, the lifting structure also includes a roller, and the roller is inserted into the interior of the lower end of the fixed seat, one end of the lower surface of the support frame is fixedly connected to a threaded seat, and the internal thread of the threaded seat is connected to a threaded rod, and one end of the threaded rod is connected to a bearing with a moving block. When the threaded rod rotates, it can rotate and move inside the threaded seat, and one end of the threaded rod can drive the moving block to move synchronously.

[0012] Preferably, the platform structure also includes a second locking seat, and the second locking seat is provided in two groups, and the lower end surfaces of the two groups of second locking seats are fixedly connected to the surface on the other side of the upper end of the support frame, support rods are inserted into the interior of the two groups of the first locking seats and the second locking seats, and there are four groups of support rods, and locking columns are fixedly connected to the surfaces on both sides of the lower ends of the four groups of support rods, and sliding grooves are opened inside the surfaces on both sides of the two groups of the first locking seats and the second locking seats, and the size of the sliding grooves is adapted to the size of the four groups of locking columns.

[0026] Embodiment 1

[0027] As Figures 1 to 5As shown in the figure, the utility model provides a mobile operating frame, which includes: a support structure 1. The support structure 1 includes a support frame 11 and a connecting plate 15. There are four groups of support frames 11. The support structure 1 also includes a support plate 12. The four corners of the lower surface of the support plate 12 are fixedly connected to the upper surfaces of the four groups of support frames 11. And the four corners of the lower surface of the support plate 12 are also fixedly connected with fixed cylinders 13. The four groups of support frames 11 are in an L shape. This design enables the lower surfaces of the four groups of support frames 11 to support between the device and the ground during use. This design can increase the contact area between the device and the ground, thereby avoiding the situation of shaking when the device is in use, thus improving the safety and stability of the device during use and reducing the potential safety hazards that may occur when workers use it.

[0028] Inserted inside the lower ends of the four groups of fixed cylinders 13 are connecting columns 14. And the surfaces of the lower ends of the four groups of connecting columns 14 are fixedly connected with a connecting plate 15. And the four corners of the lower surface of the connecting plate 15 are connected with universal wheels 16 by bearings. The upper end of the connecting column 14 is provided with a clamping ring. And the lower surface of the clamping ring is mutually attached to the lower surface inside the fixed cylinder 13. This design enables the connecting column 14 to move up or down inside the fixed cylinder 13, and can prevent the connecting column 14 from moving down excessively, thus avoiding the situation of detaching from the inside of the fixed cylinder 13. Further improving the stability of the device during use. And the device can be moved and turned through the four groups of universal wheels 16, improving the flexibility of the device.

[0029] A lifting structure 2. The lifting structure 2 includes a fixed seat 21. And the lower surface of the fixed seat 21 is fixedly connected to the upper surface of the connecting plate 15. The lifting structure 2 also includes a roller 22. And the roller 22 is inserted inside the lower end of the fixed seat 21. One end of the lower surface of the support frame 11 is fixedly connected with a threaded seat 23. And a threaded rod 24 is threadedly connected inside the threaded seat 23. And one end of the threaded rod 24 is connected with a pressing block 25 by a bearing. The threaded rod 24 can rotate and move inside the threaded seat 23, and will press the pressing block 25 to move. The upper surface of the pressing block 25 is attached to the lower surface of the support frame 11. Therefore, the pressing block 25 will not rotate when moving. And the lower surface of the pressing block 25 is attached to the outer surface of the roller 22, enabling the pressing block 25 to drive the roller 22 to rotate when moving, and driving the fixed seat 21 to move downward, thereby pressing the connecting plate 15, the four groups of connecting columns 14 and the universal wheels 16 to move downward, so that the lower surfaces of the four groups of universal wheels 16 are in contact with the ground.

[0030] Embodiment Two

[0031] As Figures 6 to 8As shown, this embodiment also proposes: a platform structure 3, the platform structure 3 includes a first snap-fit seat 31, and the first snap-fit seat 31 is provided with two groups, and the lower end surfaces of the two groups of first snap-fit seats 31 are fixedly connected to one side of the upper end surface of the support frame 11, the platform structure 3 also includes a second snap-fit seat 32, and the second snap-fit seat 32 is provided with two groups, and the lower end surfaces of the two groups of second snap-fit seats 32 are fixedly connected to the surface on the other side of the upper end of the support frame 11, and support rods 33 are inserted into the interiors of the two groups of first snap-fit seats 31 and the second snap-fit seats 32. There are four groups of support rods 33, and the surfaces on both sides of the lower ends of the four groups of support rods 33 are fixedly connected with locking columns 34. When the four groups of support rods 33 are inserted into the two groups of first locking seats 31 and second locking seats 32, the four groups of support rods 33 can be prevented from rotating. A rotation groove is provided on the surface on one side of the upper ends of the two groups of first locking seats 31 and second locking seats 32. This design allows the lower ends of the support rods 33 to rotate to one side inside the rotation groove when the support rods 33 are lifted upward, so that the four groups of support rods 33 can be folded.

[0032] Sliding grooves are respectively provided inside the two side surfaces of the two groups of first locking seats 31 and the second locking seats 32, and the height dimensions of the sliding grooves on the two side surfaces of the two groups of second locking seats 32 are greater than the height dimensions of the sliding grooves on the two side surfaces of the two groups of first locking seats 31, and the size of the locking columns 34 is adapted to the size of the sliding grooves, so that the four groups of locking columns 34 can move upward or downward inside the sliding grooves without separating from the inside of the two groups of first locking seats 31 and the second locking seats 32.

[0033] Fixed rods 35 are fixedly connected to the surfaces of opposite sides of the four groups of support rods 33, and there are multiple groups of fixed rods 35. The outer surfaces of the fixed rods 35 are snap-connected with springboards 36. The two ends of the springboards 36 can be snap-fitted with the multiple groups of fixed rods 35 according to specific circumstances to adjust the height of the springboards 36, thereby increasing flexibility in use to a certain extent.

[0034] Working principle: When the equipment is in use, it is supported by the four groups of support frames 11 and the ground. When the equipment needs to be moved, the threaded rod 24 is rotated to make the threaded rod 24 rotate and move inside the threaded seat 23, and drive the abutting block 25 to move synchronously. Then the lower surface of the abutting block 25 abuts the roller 22 to rotate, and drives the roller 22 and the fixed seat 21 to move downward. Then the fixed seat 21 abuts the connecting plate 15 and the four groups of connecting columns 14 and the universal wheels 16 to move downward, so that the lower surfaces of the four groups of universal wheels 16 are in contact with the ground, and the four groups of support frames 11, the fixed cylinder 13 and the support plate 12 are lifted upward, and the lower surfaces of the four groups of support frames 11 are separated from the ground. At this time, the equipment can be pushed to move;

[0035] When the device needs to be stored, the springboard 36 is lifted upward so that the two ends of the springboard 36 are separated from the outer surfaces of the multiple sets of fixing rods 35. Then, the four sets of support rods 33 are lifted upward respectively, driving the four sets of locking posts 34 to move inside the two sets of first locking seats 31 and the second locking seats 32. Then, the outer surfaces of the four sets of locking posts 34 are respectively attached to the upper ends of the sliding grooves on both sides of the two sets of first locking seats 31 and the second locking seats 32. Then, the four sets of support rods 33 are rotated with the four sets of locking posts 34 as the center of the circle through the rotation groove on one side surface of the upper end of the two sets of first locking seats 31 and the second locking seats 32, so that the outer surfaces of the four sets of support rods 33 are attached to each other and parallel to each other. At this time, the four sets of support rods 33 of the device are folded, and the device can be stored. The above is the entire working principle of this utility model.
