Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of grab plate car handling, in particular to a portable cable trench cover plate grab plate car device. BACKGROUND

[0002] The cable trench cover plate is a protective component covering the top of the cable trench, usually made of metal, composite material (such as glass steel), concrete, etc., which is adapted to the size and use scene of the cable trench to form a closed protective structure of the cable trench. The cable trench cover plate can provide a physical barrier for the cables in the trench, reduce mechanical impact and extrusion of the cables, slow down the aging speed of the cables, and prolong the service life.

[0003] Rat gnawing power cable damage events occur frequently, and small animal inspection has become a normalized operation work. When personnel conduct cable trench inspection, fire extinguishing bomb inspection, flood prevention and drainage inspection, station DC system insulation reduction, cable trench fire extinguishing bomb inspection and other work, cable trench cover plates need to be frequently transported. Since the surface of the cable trench cover plate is usually flat and has no protrusions, and when covering, the cover plate is tightly fitted with the surrounding recessed circle. Even with external tools, it is still time-consuming and laborious in the process of transportation, and it is easy to injure the workers due to the cover plate falling off during the transportation process, which has a great safety hazard. At the same time, due to the difference in weight and size of different specifications of cable trench cover plates, the traditional equipment is difficult to meet the diversified transportation needs.

[0004] Referring to the Chinese patent document with publication number CN117699714A, entitled "A manhole cover carrying device for municipal roads", the manhole cover carrying device for municipal roads mainly realizes the grabbing and carrying of the manhole cover through a specific mechanical structure. It includes a clamping assembly, a moving assembly, a lever assembly and a manhole cover. The lever assembly includes a flexible connecting piece for lifting the manhole cover. The manhole cover has a manhole cover hole. The clamping assembly is used to grab the manhole cover. The manhole cover with the manhole cover hole is grabbed from the road surface by the moving assembly driving device. Then the device with the grabbed manhole cover is moved to the designated position by the wheels and other moving assemblies, completing the carrying work of the manhole cover. The lever assembly uses the lever principle to easily lift the manhole cover during the lifting process.

[0005] However, the device in structure adaptability can only be better applied to the manhole cover with the manhole cover hole for carrying, and has poor applicability to the manhole cover without holes and the cable trench cover, which is difficult to meet the diversified needs of cable trench cover plate transportation. Therefore, a portable cable trench cover plate grab plate car device is needed to solve the problems in the traditional technology. SUMMARY

[0006] The application can effectively solve the problems of time-consuming, laborious, great safety hazards and difficult to meet diversified carrying needs in the traditional cable trench cover carrying process.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will be described in conjunction with the embodiments of the present invention. Figures 1-6 The technical solutions of the embodiments of the present invention will be clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention are within the scope of protection of the present invention.

[0021] Reference Figure 1 , Figure 3 and Figure 4 This embodiment provides a convenient cable trench cover grabber device, including a frame 1. A support frame 11 is fixedly installed on the top of the frame 1. The support frame 11 consists of four plates distributed in the front, back, left, and right directions, forming a rectangular frame. Two sets of transverse sliding components 2 are symmetrically arranged on the support frame 11. Two sets of longitudinal sliding components 3 are installed on the top of the transverse sliding components 2. The two sets of longitudinal sliding components 3 are symmetrically arranged in the left and right directions and are connected to the two transverse sliding components 2. The longitudinal sliding components 3 move towards each other on the transverse sliding components 2.

[0022] Each longitudinal sliding component 3 is symmetrically provided with a support plate 4. A telescopic cylinder 41 is installed on the top of the support plate 4. The piston rod of the telescopic cylinder 41 passes through the support plate 4 and is located below the support plate 4. The end of the piston rod of the telescopic cylinder 41 is connected to a powerful suction cup 42 located below the support plate 4. A vacuum pump 43 is installed on the powerful suction cup 42. The powerful suction cup 42 is an electric vacuum suction cup. After receiving a command, the vacuum pump 43 autonomously extracts the air inside the powerful suction cup 42 to create a negative pressure inside, thereby completing the gripping and fixing of the cable trench cover. When the powerful suction cup 42 needs to be removed from the cable trench cover, the vacuum pump reverses to inflate or opens the exhaust valve, which can cancel the gripping of the cable trench cover.

[0023] The frame 1 is equipped with off-road wheels 5 for adapting to rugged terrain and a battery 16. The battery 26 is connected to the off-road wheels 5 by a line to provide the necessary power to the drive components of the off-road wheels 5. The use of off-road wheels 5 can adapt to a variety of complex terrains. Whether it is a muddy path, a gravel road or a slope with a certain gradient, it can drive smoothly, ensuring the stability and reliability of the device in the process of transporting cable trench covers.

[0024] Both the transverse sliding assembly 2 and the longitudinal sliding assembly 3 consist of a motor, a bidirectional lead screw, and a slider. The overall structure of the two sets of transverse sliding assemblies 2 and the two sets of longitudinal sliding assemblies 3 is set as a rectangular frame with a hollow structure in the middle, which facilitates the driving of the powerful suction cup 42 to move the cable trench cover upward. The motor can drive the bidirectional lead screw to rotate, which in turn can make the sliders move towards each other. The displacement of the sliding assembly and the longitudinal sliding assembly 3 can adjust the position of the telescopic cylinder 41 and the powerful suction cup 42 on the four support plates 4 to adapt to the gripping of cable trench covers of various diameters.

[0025] Reference Figure 2 and Figure 5 A sliding rod 13 is installed on the frame 1 below the support frame 11. The sliding rod 13 is located between the frame 1 and the support frame 11. There are two sliding rods 13, which are installed symmetrically front and rear. Each sliding rod 13 is equipped with two electric sliders 14. The electric sliders 14 are installed symmetrically from left to right. Sensors are installed on the electric sliders 14. The top of each of the symmetrically distributed electric sliders 14 is connected to a support plate 15 for supporting the cable trench cover. There are two support plates 15, which are symmetrically distributed from left to right. The support plates 15 can slide left and right under the action of the electric sliders and sensors. When the powerful suction cup 42 lifts the cable trench cover above the support plate 15, the support plate 15 slides left and right to complete the support of the cover, which enhances the safety of the cover during the displacement process.

[0026] Refer to 5 and Figure 6 The frame 1 is equipped with a locking assembly 6 for locking the off-road wheel 5. The locking assembly 6 is configured in two sets, which act on the two wheels on the front side of the off-road wheel 5 respectively. The locking assembly 6 includes locking holes 61 opened on the off-road wheel 5. Multiple locking holes 61 are provided and are circumferentially opened on the off-road wheel 5. The frame 1 is provided with a base 62, and a locking rod 63 is slidably installed through the base 62.

[0027] A locking plate 64 is fixedly installed on the locking rod 63 to prevent it from slipping off the base 62. The locking plate 64 has a through hole 65. Two fixing rods 66 are mounted on the bracket below the base 62, arranged side-by-side, one closer to the off-road wheel 5 and the other further away. The through hole 65 on the locking plate 64 is adapted to the fixing rod 66. When the through hole 65 on the locking plate 64 is engaged with the fixing rod 66 near the off-road wheel 5, the locking rod 63 simultaneously passes through the locking hole 61 of the off-road wheel 5. When the through hole 65 on the locking plate 64 is engaged with the fixing rod 66 away from the off-road wheel 5, the locking rod 63 disengages from the locking hole 61 of the off-road wheel 5.

[0028] Reference Figure 3 and Figure 4An auxiliary plate 7 is installed at the connection between the transverse sliding component 2 and the longitudinal sliding component 3. The longitudinal sliding component 3 is mounted on the auxiliary plate 7, and an auxiliary sliding component 8 is installed on the auxiliary plate 7 to enhance the sliding of the longitudinal sliding component 3 and the support plate 4. The auxiliary sliding component 8 includes a drive motor 81. Two axle wheels 82 are rotatably mounted on the auxiliary plate 7, one of which is connected to the output shaft of the drive motor 81. An auxiliary conveyor belt 83 is connected between the two axle wheels 82. The auxiliary conveyor belt 83 is fixedly connected to the slider on the longitudinal sliding component 3. The two sliders on the longitudinal sliding component 3 are respectively connected to the front and rear conveyor belts on the auxiliary conveyor belt 83. When the auxiliary conveyor belt 83 rotates, the front and rear conveyor belts simultaneously move towards the center or separate to the sides. The drive motor 81 is set as a bidirectional motor that rotates in both directions. The movement of the auxiliary conveyor belt 83 drives the sliders on the longitudinal sliding component 3 to move synchronously, thereby achieving smooth and precise sliding of the longitudinal sliding component 3. This design can enhance the sliding stability of the longitudinal sliding component 3.

[0029] Reference Figure 4 and Figure 5 The frame 1 is equipped with a push handle 12, and the device is equipped with a remote control. During use, the displacement of the device can be controlled by pushing the handle 12 or the remote control. The battery 16, the lateral sliding assembly 2, the longitudinal sliding assembly 3, the drive motor 81, the powerful suction pump and the sensor are all connected to the external control system and controlled by the remote control.

[0030] The implementation principle of a convenient cable trench cover grabber device according to an embodiment of the present invention is as follows: When using this device, first clean the surface of the cable trench cover. Then, move the device above the cable trench cover by pushing the handle 12 or using the remote control. According to the specifications and position of the cable trench cover, the horizontal sliding assembly 2 and the vertical sliding assembly 3 are moved and adjusted by the external control system. Specifically, the motors of the horizontal sliding assembly 2 and the vertical sliding assembly 3 drive the bidirectional lead screw to rotate, which moves the slider and adjusts the position of the support plate 4, the telescopic cylinder 41, and the powerful suction cup 42 in both the horizontal and vertical directions to accurately align them with the cable trench cover. When the slider on the vertical sliding assembly 3 moves back and forth, the drive motor 81 drives the shaft wheel 82 to rotate, which in turn moves the auxiliary conveyor belt 83. The auxiliary conveyor belt 83 drives the slider on the vertical sliding assembly 3 to move synchronously, which enhances the sliding stability of the vertical sliding assembly 3 and ensures the overall smoothness and accuracy of the device's operation.

[0031] Then, the telescopic cylinder 41 is activated to bring the powerful suction cup 42 into contact with the surface of the cover plate, and the vacuum pump 43 is activated to extract the air inside the powerful suction cup 42, creating a negative pressure inside, thereby tightly adhering to the cable trench cover plate. At this time, the piston rod of the telescopic cylinder 41 retracts, driving the powerful suction cup 42 and the adsorbed cable trench cover plate to move upward.

[0032] When the cable trench cover moves upward to above the receiving plate 15, the electric slider 14 can be controlled by the external control system to move on the sliding rod 13. The sensor on the electric slider 14 provides real-time feedback of position information, so that the receiving plate 15 can slide left and right to the appropriate position to complete the receiving of the cover and prevent the cover from slipping during the movement.

[0033] Once the internal inspection of the cable trench is complete, the device can be used via an external control system and remote control to return the cover to its original position. The entire process is remotely controlled via the external control system and remote control, making operation convenient and quick. This improves the handling efficiency of cable trench covers, reduces safety hazards, and meets diverse handling needs.

[0034] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
