[0021] That is, when rainwater grate 3 located at the edge of road surface 1 and sidewalk 2 is needed to be handled, lifting device 6 can be stretched and supported on sidewalk 2, and the other supports 5 are supported on road surface 1, which effectively solves the problem of height difference between road surface 1 and sidewalk 2, provides a stable and horizontal working platform for the whole equipment, and prevents the equipment from overturning or unstable operation.

[0022] It should be noted that lifting assembly 8 is used to extract and install cast iron rainwater grate 3, which is smooth on the surface and can be adsorbed.

[0023] In the embodiment, the lifting assembly 8 comprises: fixed plate 83, configured as four, respectively fixed at the output end of four lifting motors 7;Lifting rod 84, configured as four, one end is hinged to the fixed plate 83, and the other end is hinged with universal joint 85;Connecting piece 86 is hinged to the universal joint 85;Lifting plate 81 is fixed between four connecting pieces 86;Clamping assembly 82 is configured as four, symmetrically installed in the lifting plate 81.

[0024] As a preferred embodiment, the walking frame 4 is at an angle of 45° with the rainwater grate 3 when lifting the rainwater grate 3, and the four edges of the lifting plate 81 are parallel to the four edges of the rainwater grate 3.

[0025] Among them, by installing lifting assembly 8 below walking frame 4, it can ensure that supports 5 and lifting device 6 support lifting assembly 8 in four directions, avoid the center of gravity from deviating when lifting rainwater grate 3, and cause the equipment to overturn.

[0026] In addition, visual sensor can be installed below lifting plate 81, so as to determine the relative position of lifting plate 81 and rainwater grate 3 through vision, so that lifting plate 81 is located at the middle position of rainwater grate 3, avoiding the situation that lifting rainwater grate 3 is forced to tilt due to deviation, causing jamming phenomenon.

[0027] As a preferable embodiment, the clamping assembly 82 comprises: two clamping plates 821 symmetrically and slidingly arranged in the lifting plate 81; a sliding column 822 fixed to one side of the two clamping plates 821 away from each other and slidingly connected with the lifting plate 81, a clamping spring 823 sleeved on the sliding column 822; a manual switch 824 rotationally arranged on the upper end surface of the lifting plate 81, and two handles 8241 symmetrically fixed to the top of the manual switch 824; a suction assembly 825 slidingly arranged in the lifting plate 81 and the manual switch 824; a reset disc 826 fixed to the outer wall of the suction assembly 825 and provided with a reset spring 827 between the suction assembly 825 and the lifting plate 81; a suction head 828 fixed to the lower end surface of the suction assembly 825; and an opening and closing assembly 829 arranged as two, one end symmetrically arranged on both sides of the suction assembly 825 and the other end slidingly arranged in the clamping plate 821.

[0028] As a preferable embodiment, the bottom of the two clamping plates 821 is provided with a lifting surface 8211 on one side close to each other, and the bottom of the lifting surface 8211 is provided with a guide surface 8212.

[0029] When clamping the rainwater grate 3, first determine the position through the visual sensor, then press the grids of the rainwater grate 3 through the clamping plates 821 in the plurality of clamping assemblies 82 by the guide surface 8212, so that the lifting surface 8211 supports the bottom of the grids, and the suction head 828 directly contacts the grids, then performs vacuum suction work between the suction head 828 and the grids through the suction assembly 825, thereby improving the stability during lifting.

[0030] It should be noted that when the rainwater grate 3 is slightly deformed, the well head is uneven, or the rainwater grate 3 is stuck by mud, the four lifting motors 7 can perform rapid small amplitude lifting reciprocating operation, thereby shaking the rainwater grate 3, so that the rainwater grate 3 is separated from the stuck state.

[0031] As a preferable embodiment, the suction assembly 825 comprises: a sliding cylinder 8251 slidingly arranged in the lifting plate 81 and the manual switch 824; a telescopic device 8252 fixed to the bottom of the manual switch 824 and located inside the sliding cylinder 8251; and a sealing column 8253 slidingly arranged in the sliding cylinder 8251 and fixedly connected with the output end of the telescopic device 8252.

[0032] That is, when the suction head 828 is pressed on the grids of the rainwater grate 3 by the reset spring 827, the sealing column 8253 is driven away from the suction head 828 by the telescopic device 8252 at this time, thereby performing vacuum suction work and completing auxiliary suction stabilization work.

[0034] When the rainwater grate 3 is installed, the sealing column 8253 is driven by the telescopic device 8252 to approach the adsorption head 828, so that the adsorption head 828 is separated from the adsorption state, then the limiting block 8254 is limited by the limiting ring groove 8255 by manually rotating the manual switch 824, at this time the sealing column 8253 is driven by the telescopic device 8252 to drive the sliding cylinder 8251 to move synchronously, then the two clamping plates 821 are away from each other through the opening and closing assembly 829, so as to facilitate the disengagement of the grid of the rainwater grate 3, and the installation work is completed.

[0035] It should be noted that the height of the limiting block 8254 is less than the height of the limiting ring groove 8255, which facilitates the rotation of the limiting block 8254 in the limiting ring groove 8255.

[0036] As a preferred embodiment, the opening and closing assembly 829 comprises a sliding block 8291 slidingly arranged in the clamping plate 821, a guide column 8292 fixed to the upper end surface of the sliding block 8291 and in sliding connection with the clamping plate 821, an opening and closing spring sleeved on the guide column 8292, and an opening and closing rod 8293 hingedly connected at one end to the sliding block 8291 and at the other end to the outer wall of the sliding cylinder 8251.

[0037] That is, when the sliding cylinder 8251 slides upward, it drives the opening and closing rod 8293 to rotate along the sliding block 8291, thereby pushing the two clamping plates 821 away from each other to complete the disengagement from the rainwater grate 3, and the opening and closing spring can assist the pressing of the adsorption head 828 by the return spring 827, so as to make it adhere to the grid of the rainwater grate 3, and complete the auxiliary adsorption work.

[0038] In specific implementation, when the rainwater grate 3 located at the edge of the road surface 1 and the sidewalk 2 needs to be processed, the lifting device 6 can be extended and supported on the sidewalk 2, and the remaining supports 5 are supported on the road surface 1, effectively solving the problem of the height difference between the road surface 1 and the sidewalk 2, providing a stable and horizontal working platform for the entire device, preventing the device from overturning or unstable operation, and through the four independent lifting motors 7, multi-degree-of-freedom adjustment and lifting can be carried out, ensuring that the rainwater grate 3 is smoothly and horizontally lifted or installed, avoiding jamming or damage caused by uneven force, and when the rainwater grate 3 is slightly deformed, the well mouth is uneven, or the grate is stuck by mud, through the four lifting motors 7, small amplitude lifting can be carried out quickly, so that the rainwater grate 3 is shaken, the rainwater grate 3 is easily separated from the stuck state, and when the rainwater grate 3 is clamped, the clamping plate 821 is used for preliminary clamping, and the adsorption assembly 825 is used for auxiliary adsorption, realizing the linkage operation of clamping and adsorption, and improving the clamping stability of the rainwater grate 3.
