Detailed Description

In order to make the technical solution and the advantages of the present invention clearer, the following explains embodiments of the present invention in further detail.

As shown in fig. 1, the device for quickly covering a cable trench cover plate comprises a movable bottom plate 100, a paving vehicle 300, a traction device 500, a hopper 200, an overturning bracket 400 and a propelling device 600.

The moving floor 100 and the flatcar 300 are arranged side by side along the length of the cable trench. The cable trench is a channel, and the cable cover plate covers the upper part of the cable trench and is used for guaranteeing the flatness of the ground and protecting cables in the cable trench. The lower portion of the moving base plate 100 is provided with wheels to allow the moving base plate 100 to move. The moving floor 100 is located on the upper portion of the laid cover, and the flatcar 300 is located at the front portion of the moving floor 100, at a position where no cable cover is laid in the cable trench.

Preferably, the wheels of the movable base plate 100 are disposed at the edge of the cable trench, that is, the wheels are pressed at the edge of the cable cover plate instead of the middle of the cable cover plate, so as to prevent the cable cover plate from being crushed due to the overweight of the hopper.

A hopper 200 is provided at an upper portion of the movable base plate 100, the hopper 200 being used to carry a cable cover to be laid. In the un-laid state, the hopper 200 faces upward, which facilitates the loading and unloading of the cable cover. The cable cover plate can be placed into the hopper through the forklift. In the laying state, the hopper 200 is turned by 90 degrees so that the cable cover plates horizontally placed are vertically placed, and then the cable cover plates at the edges are slid by the laying flat carriage 300 to be horizontally placed and laid on the cable trench. The upper side of the hopper 200 in its original state is flush with the front end edge of the moving base 100. I.e., the hopper 200 is rotated 90 deg. and the hopper is facing forward, as shown in fig. 11, the front side of the hopper is flush with the edge of the moving floor in the hopper facing forward position.

To facilitate loading, the front and upper sides of the hopper 200 are open and communicate with each other with the front direction pointing from a trench-laid section to a trench-unpaved section. Based on the above requirements, the specific structure of the hopper can be as follows:

since the cable cover is generally rectangular, the hopper 200 is rectangular and has a rectangular cavity.

The hopper 200 is provided with four angular columns 290, and reinforcing beams 280 fixedly connected to the columns 290 are provided on both left and right sides and a rear end side. Or, the hopper 200 is provided with four angular upright columns 290, and the upright columns 290 on the left and right sides are fixedly connected through a fixing plate. A reinforcing beam 280 fixedly connected with the two upright columns 290 is arranged between the two upright columns 290 at the rear side.

Preferably, to support the cable cover and to facilitate the installation of the propulsion apparatus 600, the bottom of the hopper 200 is provided with a rectangular frame fixedly connected to the vertical column 290. The inner ring of the rectangular frame is smaller than the periphery of the cover plate and is used for bearing the cable cover plate.

Alternatively, a load bearing bracket 190 is provided on the inside of the upright 290. The support bracket 190 is fixedly connected to the bottom of the column 290 for supporting the cable cover.

Alternatively, a rectangular frame is provided at an upper portion of the carrier bracket 190.

Preferably, the cable cover plate has a non-smooth surface and thus a large friction force is generated between the cable cover plate and the column 290 of the hopper 200 due to the weight of the cable cover plate itself. In order to reduce the labor intensity of the construction, rollers 291 or balls are provided on the front side surface of the inner surface of the front column 290 in a state where the hopper 200 faces upward on the side surface of the column 290. The axial direction of the roller 291 is perpendicular to the longitudinal direction of the vertical shaft. At this time, the friction force can be reduced when the cable cover plate is pushed in, so that the cable cover plate can roll out of the hopper 200 more easily.

In order to better define the running track of the pushing plate 630 and prevent it from shifting or tilting, rail grooves 292 are formed on the left and right sides of the vertical column 290 in the length direction. The pushing plate 630 is provided with a limiting protrusion 639 at a position corresponding to the track groove 292. The limiting protrusions 639 are slidably disposed in the track grooves 292, and the vertical state of the push plate 630 can be effectively ensured by limiting the four limiting protrusions 639.

In order to facilitate the overturning of the hopper 200, the left and right sides of the hopper 200 are provided with overturning pipes 230 with pipe orifices facing to the rear, and an overturning operating rod 240 is inserted in the overturning pipes. Since the hopper 200 and the inversion bracket 400 are rotatably coupled, the hopper 200 can be rotated. Because the hopper behind the cable cover plate has certain weight, the overall length of the turnover pipe 230 and the turnover operating rod 240 can be changed in a mode of inserting the turnover operating rod 240, so that different personnel can adjust according to the size of personal strength and the actual quality of the hopper 200, and the purpose of edge turnover is achieved.

A locking device is provided between the turnover lever 240 and the turnover tube 230 so as to keep them stable when not operated. The locking device comprises locking holes arranged on the overturning operating rod 240 and the overturning pipe 230 and locking pins inserted in the locking holes, wherein the two locking holes are overlapped when the overturning operating rod 240 is inserted, and the locking is realized by inserting the locking pins.

In order to prevent the cable cover from falling outward in the vertical state, a stopper 220 is provided on the upper edge of the rear side of the hopper 200. The restricting means 220 is movably provided with a projection toward the inside of the hopper 200. After inversion, the limiting means are located at the upper part and the projections are located inside the hopper 200, thus achieving a stop for the cable cover. Specifically, the method comprises the following steps:

the limiting device 220 comprises a return slide block 221 and a T-shaped projection 222. To facilitate the retention of the cable cover during the pushing process, a return chute 227 is provided at the upper end of the hopper 200, and when the hopper 200 is comprised of the vertical columns 290 and the reinforcing beams 280, the return chute 227 is provided at the upper portion of the vertical columns 290. The length direction of the return chute 227 coincides with the length direction of the upright post.

The return slider 221 is disposed inside the return sliding slot 227 and connected to the bottom of the return sliding slot 227 through a tension spring. The return slider 221 is provided with a slide hole in the horizontal direction. An anti-falling limiting block 226 is arranged at the end of the return chute 227. The end of the return slider 221 located inside the return chute 227 is provided with an anti-drop block 224. During the pushing process, the cable cover plate pushes the limiting device 220 outwards, and the excessive pushing process can be prevented through the matching of the anti-falling block 224 and the anti-falling limiting block 226, so that the pushing length of the cable cover plate is kept to be the thickness of the cable cover plate.

The T-shaped projection 222 is inserted into the slide hole. The end of the T-shaped projection 222 is trapezoidal with a slope at the top. The small end of the T-shaped protrusion 222 is provided with a retaining stop 223. Alternatively, the end of the T-shaped protrusion 222 is in the shape of a hook bent downward. The anti-falling stopper 223 or the hook-shaped anti-falling stopper is provided to prevent the T-shaped protrusion 222 from falling off from the slide hole. When the hopper 200 is in a vertical state, the T-shaped protrusion 222 is an inclined surface, so that the T-shaped protrusion 222 can be automatically pushed out during charging, and the T-shaped protrusion 222 can be automatically returned to play a role in limiting the cable cover plate due to the action of gravity after being turned over.

The inversion bracket 400 is used to achieve a 90 degree inversion of the hopper 200. The flip stand 400 includes the following two ways:

the turning bracket (400) includes a fixing block (410) and a turning shaft (420). The fixing blocks 410 are disposed at both sides of the moving base plate 100 and fixedly coupled to the moving base plate 100. The end of the turning shaft is rotatably connected to the fixing block 410. The bottom edge of the front side of the hopper 200 is fixedly connected with the turnover shaft 420, and when the hopper 200 consists of the upright column 290 and the reinforcing beam 280, the turnover shaft 420 is fixedly connected with the lower ends of the two upright columns at the front. The flip axis 420 can be one major axis or two minor axes. When the two short shafts are provided, the two short shafts are respectively and fixedly connected with the two upright posts. The hopper can now be rotated along the edge of the front lower end of the hopper 200.

The turning bracket 400 includes a lifting frame 430 and a turning shaft 420.

The lifting frame 430 can be controlled to be lifted by a hydraulic cylinder using a hydraulic lifting device. The lifting frames 430 are arranged at both sides of the moving base plate 100, and the fixing parts of the lifting frames 430 are fixedly connected with the sides of the moving base plate 100. The upper end of the elevating part of the elevating bracket 430 is rotatably connected with the turning shaft 420. The other end of the turnover shaft 420 is fixedly connected with the center position of the left and right side surfaces of the hopper 200. The lifting distance of the lifting frame is more than L, and L is 1/2 (L)_dj-L_db)，L_djThe length of the diagonal line of the hopper side rectangle, L_dbThe length of the short side of the hopper side rectangle. At this time, the hopper 200 rotates along the connecting line of the centers of the two side surfaces, which is more labor-saving. Can adopt the treading type hydraulic cylinder to realize upgrading and treadingThe plate may be disposed on the upper portion of the moving base 100.

The hopper 200 can be rotated by operating the turnover operation lever 240, thereby achieving 90 ° turnover of the hopper 200.

The paving vehicle 300 is used to realize the transformation of the vertical cable cover into the horizontal state by means of sliding. The spreader 300 is likewise provided with wheels, the wheels of the spreader 300 being arranged at the edge of the cable trench, i.e. the spreader 300 is arranged across the cable trench. The paving vehicle 300 includes two sliding blocks 310 and a clamping shaft 320 rotatably connected to the sliding blocks 310 at both ends. The sliding function of the sliding block 310 can be realized by providing wheels. The sliding block 310 may also be directly driven to slide, which increases the wear of the sliding block 310, and therefore a wheel approach is preferred. In order to limit and fix the cable cover and better control the sliding speed of the cable cover, a cover clamping groove 330 is provided at the upper part of the clamping shaft 320. After the front cable cover is pushed out by the pushing device 600, the cable cover located at the front edge slides down into the cover card slot 330.

To facilitate the sliding-in of the cover 900, the cover card slot 330 includes an upper slide-in portion 331 and a lower insert portion 332. The upper slide-in 331 is inverted trapezoidal with the hypotenuse adjacent to the moving floor; the insert portion 332 has a rectangular shape. The engaging shaft 320 abuts the front edge of the movable base plate 100, the inclined surface of the upper slide-in portion 331 is close to the movable base plate 100, and the cover plate is separated from the hopper and then slides into the fitting portion 332 via the inclined surface of the upper slide-in portion 331. The insertion portion 332 serves to restrict the cover plate to be smoothly moved.

Preferably, in order to automatically restore the notch of the cover plate slot 330 of the clamping shaft 320 to an upward state, a rotary spring is arranged between the clamping shaft 320 and the sliding block 310 to make the opening of the cover plate slot 330 upward; alternatively, a weight block is disposed at the lower portion of the fastening shaft 320.

The traction devices 500 are disposed on both sides of the movable floor 100 to drive the paver 300 forward. The fixed part of the traction device 500 is fixedly connected with the movable floor 100, and the end of the propelling part or the telescopic part of the traction device 500 is fixedly connected with the flatbed 300. Based on this, the traction device 500 not only can drive the paving vehicle 300 to move, but also can play a role in connecting the movable floor 100 and the paving vehicle 300. The specific structure of the traction device 500 can adopt the following two ways:

The push rod 540 is disposed parallel to the movable base plate 100, and has a rear end hinged to the lower end of the traction lever 530 and a front end fixedly connected to the sliding block 310. The track tube 550 is fixedly connected to the front ends of the two sides of the movable base plate 100 and is sleeved on the push rod 540. The track tube 550 is used to define the moving track of the push rod 540, so that the push rod keeps horizontal and keeps moving back and forth. When the push needs to be carried forward, the upper end of the traction operation rod 530 is moved from front to back by both hands, and at the moment, the push rod 540 moves from back to front, so that the push of the flatcar 300 is realized.
