[0006] Preferably, the grabbing mechanism comprises a scissor assembly and a gripper, wherein two movable ends above the scissor assembly are connected to the tension of the winch via a connecting rope, and the gripper is fixedly arranged at two movable ends below the scissor assembly.

[0007] Preferably, the pushing mechanism includes a material storage trough and a material feeding trough arranged above the base, the material storage trough is vertically connected to one side end of the material feeding trough, the cover plates are stored side by side in the material storage trough, and a pressing assembly for conveying the cover plates into the material feeding trough is provided at the end of the material storage trough away from the material feeding trough, and a pushing assembly for conveying the cover plates in the material feeding trough outward is provided at an opening on one side of the material feeding trough; a discharge port is provided at the end of the material feeding trough away from the pushing assembly.

[0008] Preferably, the pressing assembly includes a pressing plate and a spring. The pressing plate is movably arranged in the material storage trough and is crimped with the cover plate. Limiting holes are provided on the two side walls of the material storage trough along its length direction. Sliding rods are fixed on both sides of the pressing plate, which slide through the limiting holes and extend outward. Both sliding rods are fixedly connected to one end of the corresponding spring, and the other end of the spring is fixedly connected to the base close to the feeding trough.

[0009] Preferably, a limit block is fixed on the slide rod in close contact with the outer wall of the material storage trough.

[0010] Preferably, a reset handle is provided above the pressing plate.

[0011] Preferably, the pushing assembly includes a push rod, a slide groove connecting rod, a slider and a swing arm. The push rod is slidably arranged on one side of the feeding trough. One end of the push rod is used to push the cover plate toward the discharge port, and the other end is vertically fixed to the middle part of the slide groove connecting rod. The slider is slidably clamped in the slide groove in the middle part of the slide groove connecting rod. One end of the swing arm is rotatably connected to the slider, and the other end is rotatably installed on the base and connected to the power of the second motor installed on the base.

A telescopic cylinder is horizontally installed on the side away from the closing door of the waste storage box, and the piston rod of the telescopic cylinder is fixedly connected to the unloading plate.

[0014] The present invention has the following beneficial effects: 1. The sliding cooperation between the slide groove and the moving block of the present invention can effectively limit the movement of the moving block. When the first motor drives the first screw to rotate, the moving block can drive the winch and the grabbing mechanism to move forward and backward, which is more convenient for lifting and moving the cable trench cover forward and backward, and improves construction efficiency.

[0015] 2. The cooperation between the slide bar and the limit hole can effectively limit the movement of the pressure plate, and under the elastic tension of the spring, the pressure plate presses the cover plates placed side by side in the storage trough and transports them to the feeding trough until the front cover plate abuts against the inner wall of the feeding trough.

[0016] 3. When the cover plate in the storage trough is used up and needs to be reloaded, the reset handle pulls the pressure plate away from the feeding trough to reset the pressure plate and stretch the spring at the same time, and then reload a new pressure plate into the storage trough.

[0017] 4. Since the cover plate is often damaged during the construction of the cable trench, it is necessary to replace the new cover plate in time. When the new cover plate needs to be replaced, start the second motor to drive the swing arm to rotate, so that the slider can slide in the slide groove connecting rod and push the slide groove connecting rod and the push rod to slide left and right in the feeding trough. When the push rod moves to the left and pushes the cover plate at the intersection of the storage trough and the feeding trough to the discharge port of the feeding trough, as the swing arm rotates to the right, the push rod resets to the right. Under the action of the spring force, the pressure plate pushes the cover plate to refill the vacant cover plate at the intersection of the storage trough and the feeding trough, and repeats the cycle, so that all the cover plates are pushed out, which significantly improves the transmission efficiency of the cover plates.

[0018] 5. The discharge port of the feeding trough extends a certain length out of the base, so that the delivered cover is outside the base, which is convenient for cooperating with the lifting frame and the grabbing mechanism to grab and lift the newly delivered cover, and can effectively avoid the upper bracket affecting the lifting of the cover.

[0019] 6. Cable laying causes the breakage of cover plates, cable docking, stripping and other constructions, which will generate waste and garbage. This device can effectively store and collect the above construction waste through the waste storage box with an upper opening. When the waste storage box is full, open the opening and closing door, start the telescopic cylinder, drive the side wall of the waste storage box to move toward the discharge port, and push the waste in the box out to a suitable disposal area outside, making the collection and unloading of waste more convenient.

DETAILED DESCRIPTION

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.

[0022] like Figure 1-4 As shown, the present invention proposes a cable trench cover construction device, including a vehicle body, a lifting frame and a grabbing mechanism, the vehicle body includes a base 1 and a bracket 2, the bracket 2 is fixed on the base 1, the lifting frame includes a pillar 32 and a crossbar 33, and the lower end of the pillar 32 is rotatably installed above the bracket 2 through a power turntable 31. By controlling the rotation of the power turntable 31, the rotation direction of the lifting frame is adjusted, so that the lifting construction of the cable trench cover 6 is more convenient.

[0023] The cross bar 33 is vertically connected to the upper end of the support 32, and a transverse mechanism is installed on the cross bar 33 along its length direction. A winch 36 is installed on the action end of the transverse mechanism, and the grabbing mechanism is installed on the end of the pull rope of the winch 36. Specifically, the transverse mechanism includes a first screw rod 34 installed horizontally below the cross bar 33, and the first screw rod 34 is connected to the first motor power on the cross bar 33; a slide groove is opened at the bottom of the cross bar 33 along its length direction, and a moving block 35 is slidably arranged in the slide groove, and the moving block 35 is threadedly sleeved on the first screw rod 34; the winch 36 is installed on the moving block 35. The sliding cooperation between the slide groove and the moving block 35 can effectively limit the movement of the moving block 35. When the first motor drives the first screw rod 34 to rotate, the moving block 35 can drive the winch 36 and the grabbing mechanism to move forward and backward, which is more convenient for lifting and moving forward and backward of the cable trench cover 6, and improves the construction efficiency.

[0024] In this embodiment, the grabbing mechanism includes a scissor assembly 38 and a gripper 39. The two movable ends above the scissor assembly 38 are connected to the pulling of the winch 36 through a connecting rope 37, and the gripper 39 is fixed to the two movable ends below the scissor assembly 38. Under the action of gravity, the connecting rope 37 cooperates with the scissor assembly 38 to grab the heavy object through the gripper 39, which is a conventional application of the prior art, and its action principle is not repeated here.

[0025] A driving wheel is installed below the base 1, and the driving wheel can be an electric walking wheel 11, which makes it more convenient for the entire construction device to walk and move.

[0026] like Figure 2 As shown, a pushing mechanism for conveying new cover plates 6 is installed above the base 1, and the pushing mechanism includes a storage tank 5 and a feeding tank 7 arranged above the base 1, the storage tank 5 is vertically connected to one end of the feeding tank 7, and the cover plates 6 are stored side by side in the storage tank 5, and a pressing assembly for conveying the cover plates 6 to the feeding tank 7 is provided at one end of the storage tank 5 away from the feeding tank 7. The pressing assembly includes a pressing plate 51 and two springs 53, the pressing plate 51 is movably arranged in the storage tank 5 and is pressed against the last cover plate 6, and a long strip-shaped limiting hole 50 is opened on the two side walls of the storage tank 5 along its length direction, and a sliding rod 52 that slides through the limiting hole 50 and extends outward is fixed on both sides of the pressing plate 51, and a limiting block 521 is fixed on the sliding rod 52 close to the outer wall of the storage tank 5, and the limiting hole 50 can limit the movement of the two sliding rods 52 to avoid deviation in the movement of the two sliding rods 52, causing the pressing plate 51 to be deflected and stuck in the storage tank 5. The two slide bars 52 are fixedly connected to one end of the corresponding spring 53, and the other end of the spring 53 is fixedly connected to the base 1 near the feeding trough 7. The cooperation between the slide bar 52 and the limiting hole 50 can effectively limit the movement of the pressing plate 51, and under the elastic tension of the spring 53, the pressing plate 51 presses the cover plates 6 placed side by side in the storage trough 5 to be transported to the feeding trough 7 until the frontmost cover plate 6 abuts against the inner wall of the feeding trough 7.

[0027] A reset handle 510 is fixedly arranged above the pressing plate 51. When the cover plate 6 in the storage tank 5 is used up and needs to be reloaded, the reset handle 510 pulls the pressing plate 51 away from the feeding tank 7, so that the pressing plate 51 is reset and the spring 53 is stretched, and then a new pressing plate 51 is reloaded into the storage tank 5.

[0028] The thickness of the cover plate 6 matches the width of the feed trough 7, so that the feed trough 7 can only accommodate one cover plate 6 in the width direction. A discharge port is provided at the left end of the feed trough 7 away from the push assembly. A push assembly for conveying the cover plate 6 in the feed trough 7 outward is provided at the right opening of the feed trough 7. The push assembly includes a push rod 81, a slide connecting rod 82, a slider 83 and a swing arm 84. The push rod 81 is slidably arranged on one side of the feed trough 7. One end of the push rod 81 is used to push the cover plate 6 to the discharge port, and the other end is vertically fixed to the middle part of the slide connecting rod 82. The slider 83 is slidably clamped in the slide in the middle part of the slide connecting rod 82. One end of the swing arm 84 is rotatably connected to the slider 83, and the other end is vertically fixed to the output shaft of the second motor installed on the base 1.

[0029] Since the cover plate 6 is often damaged during the construction of the cable trench, it is necessary to replace the new cover plate 6 in time. When the new cover plate 6 needs to be replaced, the second motor is started to drive the swing arm 84 to rotate, so that the slider 83 can slide in the slide groove connecting rod 82 and push the slide groove connecting rod 82 and the push rod 81 to slide left and right in the feeding trough 7. When the push rod 81 moves to the left to push the cover plate 6 at the intersection of the storage trough 5 and the feeding trough 7 toward the discharge port of the feeding trough 7, as the swing arm 84 rotates to the right, the push rod 81 returns to the right, and under the elastic force of the spring 53, the pressure plate 51 pushes the cover plate 6 to re-fill the vacant cover plate 6 at the intersection of the storage trough 5 and the feeding trough 7, and repeats the cycle, thereby pushing all the cover plates 6 out, significantly improving the transmission efficiency of the cover plates 6.

[0030] Among them, the discharge port of the feeding trough 7 extends a certain length outside the base 1, so that the delivered cover plate 6 is outside the base 1, which is convenient for cooperating with the lifting frame and the grabbing mechanism to grab and lift the newly delivered cover plate 6, and can effectively prevent the upper bracket 2 from affecting the lifting of the cover plate 6.

[0031] A waste storage box 4 is installed above the bracket 2. The opening above the waste storage box 4 is a feed port, and an opening and closing door 41 is installed at the discharge port opened on one side of the waste storage box 4. An L-shaped unloading plate 42 is movably provided in the waste storage box 4 away from the closing door 41. The unloading plate 42 is arranged close to the bottom surface and side wall of the waste storage box 4. A telescopic cylinder 43 is horizontally installed on the waste storage box 4 away from the closing door 41. The piston rod of the telescopic cylinder 43 is fixedly connected to the unloading plate 42. In this embodiment, the telescopic cylinder 43 can adopt a hydraulic cylinder structure.

[0032] The cable laying causes the cover plate 6 to be broken, and the cable docking and stripping construction will generate waste and garbage. The device can effectively store and collect the above construction waste through the waste storage box 4 with an upper opening. When the waste storage box 4 is full, the opening and closing door 41 is opened, and the telescopic cylinder 43 is started to drive the unloading plate 42 to extract the side wall of the waste storage box 4 and move toward the discharge port, so that the waste in the box is pushed out to a suitable disposal area outside, making the collection and unloading of waste more convenient.
