Description

Technical Field

[0001] The utility model is applicable to the technical field of municipal engineering, and particularly relates to a conveying device for sewer grid plates. Background Art

[0002] At present, the grating plate is made of flat steel that is cross-arranged at a certain distance and cross bars, and is welded by a pressure welding machine or manually into a steel product with a square grid in the middle. It is often used as a cover plate above the sewers on municipal roads.

[0003] However, when using sewer grating plates nowadays, construction workers often stack multiple sets of grating plates on the surface of a mobile cart for convenience of subsequent use in multiple places. The transport cart with too single structure and function can only carry and place multiple sets of grating plates, but cannot quickly and conveniently limit the stacking of grating plates, which causes the grating plates to shake arbitrarily and fall from the surface when the transport cart moves, affecting the quality of its plugging installation at the sewer inlet. Therefore, we propose a transport device for sewer grating plates. Utility Model Content

[0004] The main purpose of the utility model is to provide a transport device for a sewer grating plate, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A transport device for a sewer grating plate comprises a carrying plate, a hand push frame is fixedly installed on the side surface of the top of the carrying plate, and hollow frames are slidably installed on both sides of the top of the carrying plate;

[0007] Each hollow frame has a movable groove on its side, a fixed rod is fixedly installed on the inner top surface of each movable groove, and a limit baffle is slidably sleeved on the outer surface of each fixed rod, and the limit baffle is movably installed inside the movable groove;

[0008] A rotating screw is installed at the middle end of the inner side of each hollow frame for vertical rotation via a bearing, a transmission sleeve is movably sleeved on the outer bottom surface of each rotating screw, a connecting block is fixedly installed on the outer surface of each transmission sleeve, a push rod is hinged to the end surface of each connecting block away from the transmission sleeve via a rotating shaft, and the end of the push rod away from the transmission sleeve is hinged to the outer top surface of the limit baffle via a rotating shaft.

[0009] By adopting the above technical scheme, through the rotation transmission action of the screw rod on the transmission sleeve and the transmission conversion action of the push rod, the limit baffle is rotated and stretched to perform a limit treatment from the inner wall of the grating plate mesh, thereby ensuring the stability of multiple groups of grating plates when placed, and avoiding arbitrary shaking and falling during transportation and movement, which affects the subsequent installation and use.

[0010] As an optional solution of the technical solution of the present application, a servo motor is fixedly installed on the inner top surface of each hollow frame, and the bottom surface of the servo motor transmission shaft is fixedly connected to the top surface of the rotating screw through a coupling.

[0011] By adopting the above technical solution, the power required for the rotation of the rotating screw is provided through the driving action of the servo motor.

[0012] As an optional solution of the technical solution of the present application, a sliding groove is opened inside the middle end of the carrier plate, and a sliding block is fixedly installed on the bottom surface of each hollow frame, and the sliding block is slidably inserted into the sliding groove.

[0013] By adopting the above technical solution, the movement stability of the hollow frame is ensured by the guiding sliding action of the sliding groove on the sliding block.

[0014] As an optional solution of the technical solution of the present application, sliding plates are installed on the two end surfaces of the bottom of each hollow frame, and the sliding plates are slidably fitted on the top surface of the supporting plate. A tightening bolt is screwed through the middle end of each sliding plate through a thread, and the bottom of the tightening bolt is movably fitted on the surface of the supporting plate.

[0015] By adopting the above technical solution, the stability of the hollow frame after position adjustment is ensured by the tightening and reinforcing effect of the tightening bolts.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. A device for transporting sewer grating plates according to the technical solution of the present application, wherein a hollow frame is slidably arranged on the surface of a bearing plate, and a limit baffle is movably arranged on the side of the hollow frame. Then, under the transmission conversion action of a push rod, the rotating screw rod can be rotated to convert the vertical movement force of the transmission sleeve into a push-pull force on the limit baffle, so that the limit baffle can be rotated at the side of the hollow frame to expand or contract. When the construction personnel place the grating plate on the surface of the bearing plate, the hollow frame and the limit baffle that has not yet been expanded can pass through the internal mesh of the grating plate, and then the limit baffle can be rotated and expanded to be limited from the inner wall of the mesh of the grating plate, thereby ensuring the stability of multiple groups of grating plates when placed, and avoiding arbitrary shaking and falling during transportation and movement to affect subsequent installation and use.

[0018] 2. The technical solution of the present application is a device for transporting sewer grating plates. By sliding a sliding block into a sliding groove, the hollow frame can be horizontally moved on the surface of the load-bearing plate to adjust the horizontal position of the hollow frame on the surface of the load-bearing plate, thereby ensuring that the hollow frame can be inserted into mesh holes at different positions inside the grating plate and perform a movable limit treatment on it, thereby further improving the load-bearing stability of the entire mechanism on the grating plate.

DETAILED DESCRIPTION

[0023] like Figure 1-3 As shown, the utility model provides a technical solution: a transport device for a sewer grating plate, wherein self-locking universal wheels are arranged at the four corners of the bottom of the carrying plate 1 to facilitate the movement of the carrying plate 1, hollow frames 2 are slidably installed on both sides of the top of the carrying plate 1, and sliding plates 3 are installed on the two end surfaces of the bottom of each hollow frame 2, and the sliding plates 3 are slidably fitted to the top surface of the carrying plate 1, and a tightening bolt 31 is screwed through the middle end of each sliding plate 3 through a thread, and the bottom of the tightening bolt 31 is movably fitted to the surface of the carrying plate 1.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown in FIG. 1 , a sliding groove 41 is provided inside the middle end of the carrier plate 1 , and a sliding block 4 is fixedly mounted on the bottom surface of each hollow frame 2 , and the sliding block 4 is slidably inserted into the sliding groove 41 .

[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3As shown), a servo motor 28 is fixedly mounted on the inner top surface of each hollow frame 2, and the bottom surface of the transmission shaft of the servo motor 28 is fixedly connected to the top surface of the rotating screw 23 through a coupling.

[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown in the figure, a rotating screw 23 is installed at the middle end of the inner side of each hollow frame 2 for vertical rotation through a bearing, a transmission sleeve 24 is movably sleeved on the outer bottom surface of each rotating screw 23, a connecting block 25 is fixedly installed on the outer surface of each transmission sleeve 24, and a push rod 26 is hinged on the end surface of each connecting block 25 away from the transmission sleeve 24 through a rotating shaft, and the end of the push rod 26 away from the transmission sleeve 24 is hinged to the outer top surface of the limit baffle 22 through a rotating shaft.

[0027] In some technical solutions (through Figure 1 , Figure 2 and Figure 3 As shown), each of the hollow frames 2 is provided with a movable groove 21 on its side, and a fixing rod 27 is fixedly installed on the inner top surface of each movable groove 21. Each of the fixing rods 27 is slidably sleeved on the outer surface of the fixing rod 27, and the limiting baffle 22 is movably installed inside the movable groove 21.

[0028] During operation, the tightening bolts 31 are screwed outward to make the bottom surface of the frame 2 separate from the surface of the carrier plate 1, and the hollow frame 2 is pushed to move horizontally on the surface of the carrier plate 1. The horizontal position of the hollow frame 2 on the surface of the carrier plate 1 is adjusted so that the hollow frame 2 can be inserted into the mesh inside the grid plate when the grid plate is stacked. After the multiple sets of tightening bolts 31 are screwed to make the bottom surface fully fit and tighten against the surface of the carrier plate 1, the horizontal position of the hollow frame 2 is tightened, and then the servo motor 28 is turned on by the external control switch to make the hollow frame 2 move horizontally.

Then the construction personnel hold the hand push frame 11 to push the bearing plate 1, thereby driving the grid plate to move synchronously.
