Description
Technical Field
The utility model relates to a cover plate, in particular to a special cover plate capable of sliding and hydraulically buffering opening and closing.
Background
The existing cable trench, drainage trench and other trench cover plates are all directly placed on the inner side of the trench edge, and when the operations such as inspection or dredging are carried out in the trench, the cover plates are required to be completely uncovered, so that time and labor are wasted, and particularly when the cover plates are large in size or heavy in weight, a large amount of labor cost is required to be spent.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a special cover plate which can slide and is provided with a hydraulic buffer opening and closing function, and manpower and material resources can be saved.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the special cover plate comprises a cover plate body, wherein a first pulley assembly is fixedly arranged on one side of the lower end of the cover plate body, a second pulley assembly is hinged to the other side of the lower end of the cover plate body, and the first pulley assembly and the second pulley assembly are arranged on a first track on the left side and the right side of a groove; the inner side of the lower end of the cover plate body is hinged with a hydraulic supporting rod, the other end of the hydraulic supporting rod is hinged with a third pulley assembly, and the third pulley assembly is arranged on the second track of the side wall of the groove and limited through a limiting groove.
The lower end of the limiting groove is opened and connected with the second rail through a bolt, and an outlet for the connecting plate of the third pulley assembly to extend out is formed in the upper end of the limiting groove along the length direction.
The utility model discloses a special cover plate capable of sliding and hydraulically buffering opening and closing, which has the following technical effects:
1) The cover plate body can slide along the groove under the action of the left and right first pulley assemblies, the second pulley assemblies and the first rail, and can be turned over and opened under the assistance of the hydraulic support rods, so that labor is saved for the cover or the flip cover during operation in the groove.
2) The first track and the second track are arranged, so that the cover plate is stable to install, and is not easy to shake or bend and damage due to the fact that the flatness of the edges of the grooves is adjustable by the aid of the flat track when the flatness of the edges of the grooves is insufficient.
3) Through setting up the hydraulic support pole, the hydraulic support pole not only can make the apron body laborsaving when overturning, but also can connect into whole apron body and slot simultaneously, avoids losing.
Drawings
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
fig. 1 is a sectional view (first state) of the present utility model.
Fig. 2 is an enlarged partial schematic view at a in fig. 1.
Fig. 3 is a sectional view (second state) of the present utility model.
Fig. 4 is a top view of the present utility model.
In the figure: the cover plate comprises a cover plate body 1, a first pulley assembly 2, a second pulley assembly 3, a groove 4, a first rail 5, a hydraulic support rod 6, a third pulley assembly 7, a second rail 8 and a limit groove 9.
Detailed Description
As shown in fig. 1-4, a special cover plate with hydraulic buffering opening and closing functions comprises a cover plate body 1, wherein a group of first pulley assemblies 2 are fixedly installed on the front and back of the right side of the bottom end of the cover plate body 1, pulleys of the two groups of first pulley assemblies 2 are sheaves, and the sheaves roll along a first track 5 on the right side. A group of second pulley assemblies 3 are rotatably arranged at the front and back sides of the left side of the bottom end of the cover plate body 1, pulleys of the two groups of second pulley assemblies 3 are sheaves, and the sheaves roll back and forth along a first track 5 at the left side. Two sets of hydraulic support rods 6 are transversely arranged between the first pulley assembly 2 and the second pulley assembly 3 at intervals, sleeves are arranged at the cylinder ends of the hydraulic support rods 6 of each set, and a connecting plate with holes is arranged at the piston end of each hydraulic support rod 6 of each set. The cylinder body of the hydraulic support rod 6 is detachably connected with the lug plate on the cover plate body 1 through a pin shaft and other components and can be kept rotatable. And the piston of the hydraulic support rod 6 is detachably connected with the connecting plate of the third pulley assembly 7 through a pin shaft and the like and is kept rotatable. The main body part of the third pulley assembly 7 is positioned in the limit groove 9, and the separation can be prevented by limiting through the limit groove 9; the pulley of the third pulley assembly 7 is a sheave which rolls back and forth along the second rail 8 on the left side. The second track 8 is fixed to the side wall of the trench 4.
The limiting groove 9 is of a cuboid hollow shell structure, the lower end of the limiting groove 9 is opened and is fixedly connected with the second rail 8 through a bolt, and an outlet for the connecting plate of the third pulley assembly 7 to extend out is formed in the upper end of the limiting groove 9 along the length direction. The hinge point of the connecting plate of the third pulley assembly 7 and the piston of the hydraulic support rod 6 is located outside the limit groove 9 and is at a certain distance from the outlet of the limit groove 9, so that the hydraulic support rod 6 can rotate a larger range of angles relative to the third pulley assembly 7.
When the length of the cover plate is too large, the number of the first pulley assemblies 2 and the second pulley assemblies 3 can be properly increased, the contact surface is increased, the cover plate is easier to slide, and the pulleys can be replaced by U-shaped or V-shaped pulleys as required.
Working principle and process: when working in the groove, the cover plate body 1 can move back and forth along the first track 5 through the first pulley assembly 2 and the second pulley assembly 3; when the cover plate body 1 moves forwards and backwards, the two sets of hydraulic support rods 6 and the third pulley assembly 7 are driven to move forwards and backwards together. Meanwhile, the utility model can be turned outwards at any time with the help of the hydraulic support rods 6.
