Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the following will explain the contents of the present invention in detail with reference to the accompanying drawings and the detailed description. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present invention are shown in the drawings.
As shown in fig. 1 and 2, the present embodiment discloses a manhole cover transfer device, which includes a support frame 1, a mounting frame 2 is installed at the top of the support frame 1, a horizontal movement device 3 is installed on a side surface of the mounting frame 2, a power output end of the horizontal movement device 3 is provided with a connecting piece 4, the connecting piece 4 is fixedly connected with a vertical movement device 5, and the vertical movement device 5 is connected with a manhole cover 7 through a flexible connecting piece 6.
The utility model discloses mainly through setting up support frame 1, horizontal migration device 3 and vertical migration device 5, hoist manhole cover 7 from the manhole 9 department on the jar body 8 to remove the optional position directly over non-manhole 9, avoid manhole cover 7 to lead to taking place the incident because the unexpected recap manhole 9. The utility model discloses a design is main, opens the back when manhole cover 7, puts aside it immediately, lets manhole cover 7 not have the condition of recapping manhole 9 completely to guarantee staff's life safety, simultaneously, use motion to replace the staff to open manhole cover 7, also be favorable to using manpower sparingly.
Wherein, because the height of the tank body 8 is generally between 3-4 meters, the support frame 1 and the mounting rack 2 are arranged as fixing devices for raising the height of the horizontal moving device 3 and the height of the vertical moving device 5, the height of the support frame 1 needs to be at least 1 meter higher than the height of the tank body 8, and a space is reserved for the lifting of the vertical moving device 5. The connecting piece 4 is used as a fixing piece between the horizontal moving device 3 and the vertical moving device 5, so that later-period assembly and disassembly are facilitated, and the fixing mode is more flexible compared with a fixing mode without the connecting piece.
The shape of the mounting bracket 2 is not particularly required in nature, as one embodiment of this embodiment, the mounting bracket 2 is made of C-shaped steel, two ends of the C-shaped steel are used for fixing the horizontal moving device 3, and the mounting bracket 2 is made of C-shaped steel, on one hand, considering that the support frame 1 is arranged outside the tank body 8, if the position of the vertical moving device 5 is right above the manhole 9, a rigid body needs to be arranged on the basis of the support frame 1 to extend a short distance in the direction of the manhole 9, and in addition, considering that the horizontal moving device 3 needs to occupy a longer position in the horizontal direction, in sum, the C-shaped steel is selected as one embodiment of the mounting bracket 2, and of course, any other structure capable of extending in the direction of the manhole 9 is optional.
As one embodiment of this embodiment, the horizontal moving device 3 includes mounting slots 31 disposed at two ends of the C-shaped steel, and a motor 32 mounted at one end of the inner wall of the mounting slot 31, wherein an output end of the motor 32 is connected to a driven wheel 33, the other end of the inner wall of the mounting slot 31 is provided with a tail wheel 34, the driven wheel 33 and the tail wheel 34 are connected by a chain 35 (i.e., the power output end mentioned above), and the chain 35 is fixedly connected to the connecting member 4. The driven wheel 33 is driven to rotate by the PLC control motor 32, and then a transmission process is formed by the tail wheel 34 and the chain 35, and the connecting piece 4 is installed on the chain 35, so that the connecting piece 4 can move in the horizontal direction, and a foundation is provided for the horizontal direction movement of the vertical moving device 5. In addition, in order to ensure that the connecting piece 4 always moves between the driven wheel 33 and the tail wheel 34, a limiting block can be further arranged, and specific reference can be made to the design of the induction automatic door, which is not described herein again.
The vertical moving means 5 may be any actuating structure capable of performing a linear reciprocating motion, and a preferred embodiment is provided in that the vertical moving means 5 is a hydraulic cylinder, a cylinder body of the hydraulic cylinder is installed at a side surface of a connecting member, and a piston rod of the hydraulic cylinder is connected with the manhole cover 7 through a flexible connecting member 6.
As can be seen from fig. 1, since the manhole cover 7 is generally installed at a non-axial position on the top surface of the tank body 8, the manhole cover 7 is not horizontally disposed and has a certain inclination, the flexible connecting member 6 is designed to enable the manhole cover 7 to have a certain movement space in a vertical direction when being opened/closed, when the manhole cover 7 needs to be closed, a worker can use a hand to slightly push the manhole cover 7 to align and cover the manhole cover with the manhole 9, and further, the flexible connecting member 6 is a chain.
The working principle is as follows: when the manhole cover 7 needs to be opened, the vertical moving device 5 is started, the manhole cover 7 is lifted while the piston rod is contracted, then the horizontal moving device 3 is started, the horizontal movement of the chain 35 indirectly drives the connecting piece 4, the vertical moving device 5 and the manhole cover 7 to translate, and finally the manhole cover 7 is enabled to leave the position right above the manhole 9. Similarly, the closing process of manhole cover 7 is the reverse of the opening process described above, and it should be noted that the closing process is completed by one more step than the opening process, i.e., "the manhole cover 7 is slightly pushed by the hand to align and cover with manhole 9", which cannot be replaced by a machine in this embodiment.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
