[0035] Refer to Figures 1 to 7A mobile work platform includes: a walking assembly 100, a manned basket 200 and abutment wheels. The walking assembly 100 includes a main frame 110, walking wheels 120 and a walking drive mechanism 130. The walking drive mechanism 130 is arranged on the main frame 110. The walking wheels 120 are connected to the walking drive mechanism 130. The walking drive mechanism 130 is used to drive the walking wheels 120 to rotate. Two manned baskets 200 are arranged. The upper ends of the two manned baskets 200 are respectively connected to the left and right sides of the main frame 110. A crossbeam passing position is arranged between the two manned baskets 200. The crossbeam passing position is located at the lower side of the main frame 110 and the walking wheels 120. Two groups of abutment wheel groups are provided and are respectively provided on the two manned baskets 200. The abutment wheel groups include anti-collision wheels 300 and telescopic wheels 400. The anti-collision wheels 300 and telescopic wheels 400 are rotatably provided. The rotation axis of the anti-collision wheel 300 is provided front and rear and extends toward the position where the beam passes through. The rotation axis of the telescopic wheel 400 is provided up and down. The telescopic wheel 400 is connected with a telescopic driving mechanism 500. The telescopic driving mechanism 500 is provided on the manned basket 200 and is used to drive the telescopic wheel 400 to adjust the position along the left and right directions. The telescopic wheel 400 can move to an abutment position and a yielding position. In the abutment position, the telescopic wheel 400 is closer to the position where the beam passes through relative to the anti-collision wheels 300 of the same group. In the yielding position, the telescopic wheel 400 is farther away from the position where the beam passes through relative to the anti-collision wheels 300 of the same group.

[0036] Before hoisting the working platform, the telescopic wheel 400 is retracted first, so that the telescopic wheel 400 is further away from the crossbeam passing position relative to the anti-collision wheel 300, and then the working platform is hoisted. During the hoisting process, even if the manned basket 200 is close to the crossbeam, it can be abutted by the anti-collision wheel 300 to protect the manned basket 200. The anti-collision wheel 300 can rotate during the descent of the working platform, so as not to affect the hoisting. After the hoisting is completed, the telescopic drive mechanism 500 drives the telescopic wheel 400 to change its position toward the crossbeam passing position, so that the telescopic wheel 400 exceeds the position of the anti-collision wheel 300 and abuts against the crossbeam, so that the manned basket 200 is supported and will not fall over. Moreover, when the walking drive mechanism 130 drives the walking wheel 120 to rotate and the working platform moves, the manned basket 200 supported by the telescopic wheel 400 will not scrape against the crossbeam, and the movement is smooth and stable.

[0037] In the embodiment, in each abutment wheel group, four telescopic wheels 400 are provided, and the four telescopic wheels 400 are relatively distributed at the front upper, front lower, rear upper and rear lower positions, respectively. The telescopic drive mechanism 500 is provided in a one-to-one correspondence with the telescopic wheels 400 and can adjust the left and right positions of the corresponding telescopic wheels 400 separately. By providing the telescopic wheels 400 at the front upper, front lower, rear upper and rear lower, a four-point support can be formed, and each telescopic wheel 400 can be adjusted separately, so as to better adapt to the crossbeam and make the movement of the working platform more stable. In some embodiments, telescopic wheels 400 can also be added on the basis of the above positions.

[0038] In an embodiment, the telescopic driving mechanism 500 includes a first connection seat 510, a driving screw 520, and a first wheel frame 530. The first connection seat 510 is fixed to the manned basket 200. The driving screw 520 is arranged in the left-right direction. The driving screw 520 is pivotally connected to the first connection seat 510 with its own axis as the rotation axis and is restricted from axial movement. The first wheel frame 530 is movably arranged on the first connection seat 510 and can move relative to the first connection seat 510 in the left-right direction. The rotational freedom of the first wheel frame 530 around the axis of the driving screw 520 is restricted. The first wheel frame 530 is provided with a threaded hole, and the driving screw 520 is threadedly connected to the threaded hole of the first wheel frame 530. The telescopic wheel 400 is connected to the first wheel frame 530. When the position of the telescopic wheel 400 needs to be adjusted, the driving screw 520 is rotated. The driving screw 520 drives the first wheel frame 530 to move left and right through the threaded structure, thereby driving the telescopic wheel 400 to move left and right to achieve position adjustment. The above structure for realizing the left-right movement of the telescopic wheel 400 is simple, the adjustment and positioning of the threaded structure are good, and the position is stable.

[0039] In an embodiment, the rotation of the driving screw 520 can be realized by providing a pivot hole in the first connection seat 510 to cooperate with the driving screw 520. A snap ring can be installed on the driving screw 520, and the snap ring abuts against the first connection seat 510 to restrict the axial movement of the driving screw 520. It can be imagined that in some other embodiments, other structures can also be used to realize the rotational connection of the driving screw 520 to the first connection seat 510. For example, a pivot shaft is provided at the end of the driving screw 520, and the first connection seat 510 is provided with a pivot hole to cooperate. In addition, in order to restrict the axial movement of the driving screw 520, a clamping surface can also be provided on the first connection seat 510, and a corresponding step is provided on the driving screw 520 to cooperate with the clamping surface, thereby realizing the axial positioning of the driving screw 520.

[0040] In an embodiment, the first connection seat 510 is provided with a sliding cavity extending in the left-right direction, and the first wheel frame 530 is slidably arranged in the sliding cavity, thereby realizing its left-right movement. The sliding cavity is a cavity with a non-circular cross-section, and the first connection seat 510 is adapted to the sliding cavity, so that the rotation of the first wheel frame 530 can be restricted through the sliding cavity. It can be imagined that in some other embodiments, a left-right extending chute can also be provided on the first wheel frame 530, and a slider is provided on the first connection seat 510. The slider and the chute are slidably matched, thereby realizing the left-right movement of the first connection seat 510 and also realizing the function of restricting the rotation of the first wheel frame 530.

[0041] In the embodiment, the driving screw 520 corresponding to the upper front and upper rear retractable wheels 400 is connected with a first operating handle 540 for driving the driving screw 520 to rotate. The driving screws 520 corresponding to the lower front and lower rear retractable wheels 400 are respectively connected with a linkage mechanism 600. The linkage mechanism 600 includes a second connecting seat 610, a linkage rotating shaft 620, a second operating handle 630 and a synchronization structure 640. The second connecting seat 610 is fixed to the manned basket 200. The linkage rotating shaft 620 is arranged in the left-right direction and is pivotally connected to the second connecting seat 610 with its own axis as the rotation axis. The second operating handle 630 is connected to the linkage rotating shaft 620 and is used for driving the linkage rotating shaft 620 to rotate. The synchronization structure 640 connects the linkage rotating shaft 620 and the corresponding driving screw 520 so that the linkage rotating shaft 620 and the driving screw 520 can rotate synchronously. The first operating handle 540 corresponding to the upper front retractable wheel 400 and the second operating handle 630 of the linkage mechanism 600 corresponding to the lower front retractable wheel 400 are arranged side by side at the upper part of the manned basket 200. The first operating handle 540 corresponding to the upper rear retractable wheel 400 and the second operating handle 630 of the linkage mechanism 600 corresponding to the lower rear retractable wheel 400 are arranged side by side at the upper part of the manned basket 200. When adjusting the retractable wheels 400 at the upper front and upper rear positions, the corresponding driving screw 520 can be directly driven to rotate by the first operating handle 540. When adjusting the retractable wheels 400 at the lower front and lower rear positions, the second operating handle 630 can be operated to drive the linkage rotating shaft 620 to rotate. The linkage rotating shaft 620 drives the driving screw 520 through the synchronization structure 640, so as to realize the adjustment of the positions of the retractable wheels 400 at the lower front and lower rear positions. Since the first operating handle 540 and the second operating handle 630 for respectively adjusting the retractable wheels 400 at the upper front and lower front positions are arranged side by side at the upper part of the manned basket 200, and the first operating handle 540 and the second operating handle 630 for respectively adjusting the retractable wheels 400 at the upper rear and lower rear positions are arranged side by side at the upper part of the manned basket 200, it is convenient for the construction personnel to sequentially adjust the retractable wheels 400 at the upper front and lower front positions, and the retractable wheels 400 at the upper rear and lower rear positions at one height position, avoiding squatting or bending down to adjust, and the operation is convenient.

[0042] In the embodiment, the driving screws 520 corresponding to the lower front and lower rear retractable wheels 400 are also connected with the first operating handle 540, and the left and right positions of the lower front and lower rear retractable wheels 400 can also be directly adjusted by operating the first operating handle 540 according to the actual situation and needs.

[0043] In an embodiment, the synchronization structure 640 is a timing belt structure, which includes a timing belt 641 and two timing pulleys 642. The two timing pulleys 642 are coaxially connected to the linkage rotating shaft 620 and the driving screw 520 respectively. The timing belt 641 is sleeved on the two timing pulleys 642 and tensioned. Thus, when the linkage rotating shaft 620 rotates, the driving screw 520 can be driven to rotate through the timing belt 641. It can be imagined that in other embodiments, the synchronization structure 640 is not limited to the structure of the timing belt 641. For example, a worm and worm gear can also be used to achieve the long-distance linkage between the linkage rotating shaft 620 and the driving screw 520. It can be understood that in this field, there are many implementation manners for enabling two rotatable shaft members to rotate synchronously. Those skilled in the art can make specific configurations according to the actual situation.

[0044] It can be imagined that in other embodiments, other telescopic driving mechanisms 500 can also be used to drive the telescopic wheel 400 to move left and right. For example, an electric push rod can be used. The telescopic wheel 400 is arranged on the electric push rod, and the telescopic wheel 400 is driven to move left and right through the electric push rod. It can be understood that in this field, there are many implementation manners for driving a component to adjust its position along a predetermined direction. Those skilled in the art can make configurations according to the actual situation.

[0045] In an embodiment, in each set of abutting wheel sets, the anti-collision wheels 300 are arranged in pairs. The two anti-collision wheels 300 in a pair are respectively arranged at the front and rear of the manned basket 200. With the above structure, the protection of the manned basket 200 is better. In an embodiment, a second wheel frame 210 is fixed on the manned basket 200, and the anti-collision wheel 300 is connected to the second wheel frame 210.

[0046] In an embodiment, a handle rod 220 is connected to one side of the manned basket 200 near the position where the cross beam passes through. The handle rod 220 is arranged in the front-rear direction, so that construction workers can hold it conveniently, improving the operation safety.

[0047] In an embodiment, the vertical position of the handle rod 220 is adjustable, so as to facilitate adjustment and use.

[0048] In an embodiment, a pair of connecting rods 230 are provided on the manned basket 200. The connecting rods 230 are arranged vertically, and the two paired connecting rods 230 are arranged front and back. Both ends of the handle rod 220 are slidably arranged on the two connecting rods 230, so that it can move up and down. A plurality of pin holes are formed in the connecting rods 230 along the vertical direction. Activity pins 240 are respectively arranged at both ends of the handle rod 220, and the activity pins 240 can be inserted into or withdrawn from the pin holes. When it is necessary to adjust the vertical position of the handle rod 220, the activity pins 240 can be withdrawn from the pin holes, and then the handle rod 220 is moved up and down to a suitable position. Finally, the pins are reinserted into the pin holes to position the vertical position of the handle rod 220. It can be imagined that the handle rod 220 can also adopt other structures to realize the adjustment of the vertical position. In this field, there are many implementation ways to realize the position adjustment of components along a predetermined direction, and those skilled in the art can reasonably configure according to the actual situation.

[0049] In an embodiment, the walking wheels 120 are divided into two groups. The two groups of walking wheels 120 are respectively arranged at the front and rear of the main body frame 110, and two sets of walking driving mechanisms 130 are arranged and respectively correspond to the two groups of walking wheels 120. With the above structure, the support of the main body frame 110 is stable.

[0050] In an embodiment, the walking driving mechanism 130 includes a walking driving shaft 131 and a third operation handle 132. The walking driving shaft 131 is arranged in the left-right direction. The walking driving shaft 131 is pivotally connected to the main body frame 110 with its own axis as the rotation axis. The walking wheel 120 is connected to the walking driving shaft 131 and rotates synchronously with the walking driving shaft 131. The third operation handle 132 is connected to the walking driving shaft 131. When the walking driving shaft 131 is driven to rotate by the third operation handle 132, the walking wheels 120 can be driven to rotate, so as to realize the walking movement of the working platform.

[0051] In an embodiment, the third operation handles 132 are arranged in pairs. The two paired third operation handles 132 are connected to the left and right ends of the walking driving shaft 131 and respectively correspond to the two manned baskets 200. With the above structure, it is convenient for the construction workers at the two manned baskets 200 to operate the mobile working platform together or separately.

[0052] In an embodiment, a braking gear 133 that rotates synchronously is connected to the walking driving shaft 131. An activity bolt 134 is arranged on the main body frame 110. The activity bolt 134 can be inserted into the tooth grooves of the braking gear 133 to realize the braking operation and avoid the movement of the working platform during operation.

[0053] In the embodiment shown in the drawings, a manual walking drive mechanism 130 is adopted. In some embodiments, an electric walking drive mechanism 130 can also be adopted. The electric walking drive mechanism 130 can include a motor, and the walking wheels 120 are driven to rotate by the motor.

[0054] In practical applications, after the work platform is hoisted onto the cross beam, it is easy for the position of the walking assembly 100 to be skewed relative to the cross beam, and the walking direction of the walking assembly 100 is not parallel to the length direction of the cross beam when the walking assembly 100 is walking, resulting in the subsequent deviation of the movement of the work platform. Moreover, due to the structure limitation, it is also difficult to adopt a turning structure for the walking wheels 120. To this end, the following structure can be selected: The walking assembly 100 includes a wheel frame and a fixed frame. The upper end of the manned basket 200 is fixed to the wheel frame. The walking wheels 120 and the walking drive mechanism 130 are arranged on the wheel frame. The fixed frame is connected to the wheel frame. A lifting mechanism is arranged between the wheel frame and the fixed frame. The lifting mechanism is used to drive the wheel frame to lift relative to the fixed frame. The fixed frame is provided with telescopic feet. The telescopic feet can adjust the length in the up and down directions. A connecting plate is fixed to the lower end of the telescopic feet. The connecting plate is rotatably connected to a support chassis and the rotation axis is arranged up and down. Thus, the wheel frame and the manned basket 200 as a whole can rotate relative to the support chassis to adjust the position. When the walking assembly 100 is skewed, the telescopic feet are adjusted to make their lengths longer, so that the support chassis supports on the cross beam. Then, the wheel frame is driven to rise by the lifting mechanism, so as to lift the walking wheels 120. At this time, the work platform as a whole is supported by the support chassis. By adjusting the left and right positions of each telescopic wheel 400, the wheel frame and the manned basket 200 as a whole are driven to rotate by pressing against the cross beam to correct the position of the work platform. After the position is corrected, finally, the wheel frame is lowered by the lifting mechanism, and the length of the telescopic feet is adjusted to be shortened, so as to lift the support chassis, and the work platform is supported on the cross beam again by the walking wheels 120 of the wheel frame. By adopting the above structure, it is convenient to adjust the position of the work platform after hoisting and avoid the situation of walking skew. In the above implementation structure, the lifting mechanism can adopt some lifting platforms, such as scissor lifting platforms, or some manual lifting mechanisms, such as jacks, etc. In the embodiment, the telescopic feet can include two pipe fittings, and the two pipe fittings are threadedly connected to each other, so that the telescopic feet can be extended and shortened by relatively rotating the two pipe fittings.

[0055] In the above structure, a lifting mechanism is required to lift the manned basket 200, and the load is relatively large. For this, the following solution can also be adopted to adjust the position of the working platform: A steering mechanism separate from the mobile working platform is provided. The steering mechanism includes a base and a rotating seat. The base is used to be fixed on the upper side of the cross beam, and the rotating seat is rotatably arranged on the upper side of the base around a vertical axis. The rotating seat is provided with a lane groove, and the lane groove is a through groove. During use, the steering mechanism is installed on the front side of the mobile working platform, and then the mobile working platform is driven to move forward, so that the walking wheels 120 enter the lane groove, and the whole mobile working platform is supported on the rotating seat. Then, by adjusting the left and right positions of each telescopic wheel 400 in the same way, the position of the whole mobile working platform is rotated and adjusted through the rotating seat to achieve position correction. After the position correction is completed, the mobile working platform is driven to move forward to leave the lane groove. The above structure does not require lifting the manned basket 200, and the structure is simple and easy to implement. In the above implementation structure, the base can be provided with a clamping structure. The base is lapped on the cross beam and fixed by clamping the front and rear sides of the cross beam through the clamping structure.

[0056] In practical applications, in order to facilitate the construction personnel at each manned basket 200 to carry out construction flexibly, in some embodiments, the upper end of the manned basket 200 is slidably arranged on the walking assembly 100 in the front-rear direction. A manned basket driving mechanism for driving the manned basket 200 to move forward and backward relative to the walking assembly 100 is arranged between the manned basket 200 and the walking assembly 100. Thus, the construction personnel can move the manned basket 200 forward and backward separately according to their own construction needs, without the need for the whole working platform to move, and the construction operation is more flexible. In the embodiment, the manned basket driving mechanism can include a rotating shaft, a gear and a rack. The rotating shaft is rotatably arranged on the manned basket 200 in the left-right direction. The gear is coaxially connected to the rotating shaft and rotates together with the rotating shaft. The rack is fixed on the walking assembly 100 in the front-rear direction. The gear and the rack are engaged. The rotating shaft is provided with a handwheel or connected to a motor. By driving the rotating shaft to rotate, the gear rotates and moves along the rack, so as to realize the forward and backward movement of the manned basket 200 relative to the walking assembly 100. Of course, it can be imagined that the manned basket driving mechanism is not limited to the above implementation manner. For example, it can also adopt a structure such as an electric push rod for driving. In order to make each manned basket 200 move forward and backward smoothly relative to the walking assembly 100, the following structure can preferably be further adopted: The middle part of the upper end of the manned basket 200 is slidably arranged on the walking assembly 100 in the front-rear direction. The front part and the rear part of the upper end of the manned basket 200 are respectively provided with a sliding support structure. The sliding support structure includes a connecting frame and a lapping wheel. The lapping wheel is rotatably arranged on the connecting frame and the rotation axis is arranged left and right. The connecting frame is installed on the manned basket 200, and the lapping wheel is used for lapping on the upper end surface of the cross beam. Thus, when the manned basket 200 moves forward and backward relative to the walking assembly 100, support can be provided for the manned basket 200. In the embodiment, the connecting frame is detachably arranged, so as not to affect the hoisting of the working platform.

[0057] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0058] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
