Description

Technical Field

[0001] The utility model belongs to the field of concrete cover plate installation, and specifically relates to a concrete cover plate clamping device. Background Technique

[0002] In the electric power construction industry, there are many channels in the on-site construction environment, and the consumption of concrete cover plates is large. Especially for cable trenches, after the cables are installed, the cover plates need to be installed as soon as possible to reduce the risk of cable damage.

[0003] At present, the conventional installation method of small-channel concrete cover plates in the prior art is to install them by hooking the lifting rings of the cover plates with hooks or by clamping them with a clamping device.

[0004] However, the method of driving the cover plate to move by a hook has poor stability, which easily causes the cover plate to shake and shift in the air, resulting in the need for secondary adjustment after the movement of the cover plate is completed to complete the installation, which relatively affects the work efficiency.

[0005] The existing clamping device only clamps the cover plate through two groups of clamping plates arranged. Since the inner side of the clamping plate and the outer side of the cover plate are both flat surfaces, and it is relatively difficult to clamp only through the clamping forces on both sides, the friction between the two is low, which easily causes the cover plate to slip in the air, not only increasing the construction cost, but also posing a threat to the personal safety of the staff. Content of the Utility Model

[0006] In view of the above problems existing in the prior art, the main purpose of the present utility model is to provide a concrete cover plate clamping device.

The ends of the connecting rods far away from the lifting plate are rotatably connected with the clamping plates. The bottom of the inner wall of the housing is fixedly connected with an electric telescopic rod. The output end of the electric telescopic rod is fixedly connected with the lifting plate.

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please refer to Figures 1 - 5 , a concrete cover clamping device, comprising a housing 1, both sides of the bottom of the housing 1 are slidably connected with clamping plates 2, a plurality of rotating shafts 14 are equidistantly and rotatably connected inside the two clamping plates 2, a plurality of rotating plates 3 are fixedly connected to the outer parts of the groups of rotating shafts 14, a sliding rod 5 is slidably connected to the top of the housing 1, a pull ring 6 is fixedly connected to the top of the sliding rod 5, a transmission component is arranged inside the housing 1, and a linkage component is arranged inside the clamping plate 2.

[0024] Specifically, the transmission component includes a lifting plate 8, the lifting plate 8 is fixedly connected to the bottom of the sliding rod 5 and extends into the housing 1, both sides of the outer part of the lifting plate 8 are symmetrically and rotatably connected with connecting rods 9, the ends of the connecting rods 9 far away from the lifting plate 8 are rotatably connected with the clamping plates 2, the bottom of the inner wall of the housing 1 is fixedly connected with an electric telescopic rod 7, and the output end of the electric telescopic rod 7 is fixedly connected with the lifting plate 8. The linkage component includes racks 10, the racks 10 are respectively fixedly connected to both sides inside the housing 1, rotating rods 11 are rotatably connected inside the two clamping plates 2, transmission gears 12 are fixedly connected to the tops of the rotating rods 11, the transmission gears 12 are meshed with the racks 10, a plurality of first bevel gears 13 are fixedly connected to the outer parts of the rotating rods 11 at equal distances corresponding to the rotating shafts 14, and a plurality of second bevel gears 15 are fixedly connected to one ends of the outer parts of the rotating shafts 14, and the first bevel gears 13 are meshed with the second bevel gears 15.

[0025] Through the above technical solution, when manually clamping the concrete cover plate, the electric telescopic rod 7 is not controlled and is in a freely telescopic state. First, hold the device by the handle 4, then place the clamping plates 2 on both sides outside the concrete cover plate, and then manually pull up the pull ring 6 to drive the sliding rod 5 to rise on the lifting plate 8. At the same time, the spring 17 can be compressed, causing the spring 17 to deform. This makes the lifting plate 8 drive one end of the connecting rod 9 to move upward, and through the connecting rods 9 on both sides, the corresponding clamping plates 2 are pulled to slide inward until the anti-slip pads 19 on the inner sides of the clamping plates 2 are in close contact with the concrete cover plate and clamp the concrete cover plate. Moreover, the anti-slip pads 19 come into contact with the concrete cover plate first, which not only leaves space for the rotating plate 3 to move but also increases the friction with the concrete cover plate. During the movement of the clamping plates 2, the transmission gear 12 can be driven to move accordingly. The transmission gear 12 rotates self-driven through the meshing relationship with the rack 10, thereby driving the bottom rotating rod 11 and multiple first bevel gears 13 to rotate. The first bevel gears 13 then drive the corresponding second bevel gears 15 and the rotating shaft 14 to rotate through the meshing relationship. The rotating shaft 14 can drive the external rotating plate 3 to rotate upward, providing an upward pushing force to the concrete cover plate through the side wall of the concrete cover plate, improving the fixing stability. When it is necessary to clamp the concrete cover plate by a machine, the installation mechanism of the machine is connected to the installation block 18, and the telescopic movement of the output end of the electric telescopic rod 7 is controlled by an external controller. Clamping the concrete cover plate can be achieved by the same principle as above. The device clamps the concrete cover plate through two clamping plates 2, which can drive the concrete cover plate to move with high stability. Compared with the hoisting method, it can avoid the concrete cover plate from shaking and tilting, ensuring the subsequent installation stability and thus reducing the installation difficulty. Moreover, during the process of clamping the concrete cover plate by the two clamping plates 2, the rotating plate 3 can be driven to rotate upward, thereby providing an upward thrust to the concrete cover plate through the rotating plate 3, while increasing the friction with the concrete cover plate, further improving the clamping stability of the concrete cover plate and preventing the device from dropping the concrete cover plate during the process of driving it to move in the air.

[0026] Specifically, a spring 17 is arranged between the inner wall of the housing 1 and the lifting plate 8 outside the sliding rod 5. A handle 4 is fixedly connected to the top of the housing 1, and an anti-slip layer is arranged outside the handle 4. Limiting rods 16 are fixedly connected to both sides inside the housing 1, and the two clamping plates 2 are respectively slidably connected to the outer sides of the limiting rods 16.

[0027] Through the above technical solution, the spring 17 arranged can drive the clamping plates 2 on both sides to automatically return when the pull ring 6 is released, and the anti-slip layer arranged can increase the friction with the staff's hand and improve the holding stability.

[0028] Specifically, mounting blocks 18 are fixedly connected to the upper sides of both outer sides of the housing 1. Anti-slip pads 19 are fixedly connected to both sides of the rotating plate 3 on the outside of the clamping plate 2. The electric telescopic rod 7 is electrically connected to an external controller, and the anti-slip pad 19 is made of rubber material.

[0029] Through the above technical solution, the device can be easily installed on a hoisting machine through the mounting block 18, and the external controller facilitates the staff to quickly control the electric telescopic rod 7.

[0030] When in use, when manually clamping the concrete cover plate, the electric telescopic rod 7 is not controlled and is in a freely telescopic state. First, hold the device through the handle 4, then place the clamping plates 2 on both sides outside the concrete cover plate, and then manually pull up the pull ring 6 to drive the sliding rod 5 to rise on the lifting plate 8. At the same time, the spring 17 can be compressed, causing the spring 17 to deform, so that the lifting plate 8 drives one end of the connecting rod 9 to move upward, and the corresponding clamping plates 2 are pulled to slide inward through the connecting rods 9 on both sides until the anti-slip pads 19 on the inner sides of the clamping plates 2 are in close contact with the concrete cover plate and clamp the concrete cover plate at the same time. Moreover, the anti-slip pads 19 come into contact with the concrete cover plate first, which not only leaves space for the rotating plate 3 to move, but also increases the friction with the concrete cover plate. During the movement of the clamping plates 2, the transmission gears 12 can be driven to move accordingly. The transmission gears 12 rotate self-driven through the meshing relationship with the racks 10, thereby driving the bottom rotating rods 11 and multiple first bevel gears 13 to rotate. The first bevel gears 13 drive the corresponding second bevel gears 15 and the rotating shafts 14 to rotate through the meshing relationship. The rotating shafts 14 can drive the external rotating plates 3 to rotate upward, and then provide an upward pushing force to the concrete cover plate through the side wall of the concrete cover plate, improving the fixing stability. When it is necessary to clamp the concrete cover plate by a machine, connect the installation mechanism of the machine with the installation block 18, and control the telescopic movement of the output end of the electric telescopic rod 7 through an external controller. According to the same principle as above, the concrete cover plate can be clamped. The device clamps the concrete cover plate through two clamping plates 2, which can drive the concrete cover plate to move and has high stability. Compared with the hoisting method, it can avoid the concrete cover plate from shaking and tilting, ensuring the subsequent installation stability and thus reducing the installation difficulty. Moreover, during the clamping process of the two clamping plates 2 on the concrete cover plate, the rotating plate 3 can be driven to rotate upward, so as to provide an upward thrust to the concrete cover plate through the rotating plate 3, while increasing the friction with the concrete cover plate, further improving the clamping stability of the concrete cover plate and preventing the device from dropping the concrete cover plate during the air movement. The spring 17 is provided to drive the two clamping plates 2 to automatically return when the pull ring 6 is released. The anti-slip layer is provided to increase the friction with the staff's hand and improve the holding stability. The installation block 18 is provided to facilitate the installation of the device on the hoisting machine. The external controller is provided to facilitate the staff to quickly control the electric telescopic rod 7.
